The photo above shows remainder of the Quiet Ride Solutions floor kit [ the "blue strips" shown in the photo are the adhesive covering for the DynaMat vibration reducing material included in the Quiet Ride kit ] , the Hurst automatic floor shifter, the Wise Guys seat tracks with risers and of course the Factory Service Manual.

The interior has now entered the mock up stage.






Mock up of interior begins with routing the rear cab light harness ; the harness follows the same route as the factory harness did. The new harness has more feeds than the OEM harness due to the additional console courtesy lights to be installed a little further along in this project. This fabricated harness, as with all other wire harness fabrication for this vehicle, is color-coded and has a detailed schematic, and is placed in the service manual for this vehicle as a reference.

The courtesy lights will be set to operate automatically on a door ground switch, however, there is a cut off toggle for the circuit should the doors be open for an extended period of time ; like at a show or a meet.

A little mock up tease...

...just to give you an idea of where I am headed with this El Camino style interior conversion of this 1971 Chevrolet C-10 Shortbed Fleetside Pick-up Truck.

I don't care too much for carpets that have been cut or slit to clear brackets and mechanical access portals. The cuts and slits stretch and degrade the form fit of the carpet over time. The integrity of the carpet holds much longer when the carpet is brass grommeted for mounting holes and access ports. This is a tedious task to perform as it entails many trial fits of the carpet to have the various grommet punches align with various mounting holes properly. However, the effort is well worth it when one considers the end result of grommets vs the cut n slash approach.

The seat in the photo does not have the tracks or risers installed on it as of yet.
Before mounting the shifter, the seat needs to be on its tracks and risers and bolted to the floor. Custom interior modification of 1971 Chevrolet C-10 Shortbed Fleetside Pick-up Truck.

Ok...enough tease...it all comes out again.

Before continuing with the Quiet Ride Solutions damper / insulation install and the driver side firewall pad, several different mechanical aspects of this particular build need to be tasked.

The mounting lugs for the Hurst Pro-Matic 2 Ratchet Shifter need to be installed in the floorpan tunnel along with creating the shifter cable access hole, this has to be done so that the insulation can be punched at those points. A tedious task, yes, and that is why it ends up as a quiet ride.

However, before mounting the shifter, the seat needs to be on its tracks and risers and bolted to the floor.

After installing the tracks and risers on the seat, I centerlined the cab frame steering column port to the driver area floor and trial fit the seat for optimal fore / aft moment and recline position. Once it was dialed-in I scribed the footprint of the track into the floorpan. Then I fabricated the seat mount / pan reinforcement bars out of 1/4 inch steel plate.

These bars, of course, install under the pan with only the studs entering the interior and are the same length / width as the seat mounting foot. Since this was a bench seat truck, the OEM seat mountings do not align with bucket seats. The function of these bars copies the factory mount technique by clamping the seat foot to the floor pan and thereby distributing seat weight while strengthening the pan structure.

In other words, if by some odd quirk of misfortune this vehicle were to be involved in a, let's say, high speed roll-over accident ; the seats will not rip-out of the floor.

OEM style seat reinforcement along with, wearing a proper personal safety restraint, significantly reduces the chance of being ejected from a vehicle during a roll over.

I already have 95 percent of the parts for this vehicle build, however, the restraint system is part of the 5 percent of parts I have as yet to acquire. I'm leaning towards Simpson due to the fact they have restraint systems utilizing the factory seat belt mounting points. The 1971 has a OEM three-point system. More on this later as I get closer to that finishing touch stage of the build.
Now that the seat is bolted in, the console and the shifter positions can be mocked-up for optimum reach / access and their respective positions scribed to the floorpan. Custom interior modification of 1971 Chevrolet C-10 Shortbed Fleetside Pick-up Truck

Then it all goes back in again.

Now that the seat is bolted in, the console and the shifter positions can be mocked-up for optimum reach / access and their respective positions scribed to the floorpan.

Since this Hurst shifter functions either as a drop-in-drive or a ratchet, I temporarily re- installed the custom TEMPERATURE gauge pod that I created for this vehicle build : the pod contains AutoMeter Pro Comp electric Water, Engine and Transmission 2 5/8 inch gauges.[ more on this later in the mechanical section of this web site. ]

The position of the shifter needed to have ample hand clearance for PRND21 selection, in both normal and ratchet modes. between the gauge pod and the console ; along with a comfortable shifter knob hand-rest in D.

This process entails quite a bit of mock-up positioning of the shifter assembly in the various selector positions. A time consuming task that is required to find the optimum mounting location.

This second gauge pod photo shows a more clearer view of the backside custom made Water, Engine and Transmission TEMPERATURE gauge pod mount. Notice the quick disconnect wiring harness. This is yet another custom interior modification of the 1971 Chevrolet C-10 Shortbed Fleetside Pick-up Truck that I have fore sale.

The gauge pod is designed with a male / female quick disconnect wire harness.

This concept bundles the engine sensor harness in one neat package so the wiring is harnessed and not strewn about the under-dash like so much "spa get tee".

Removal and installation of the pod is simply a matter of disconnecting the electrical plugs and removing two mounting bolts.

It is a custom trick item that complements the information contained in...
The gauge pod was designed to complement this fully loaded gauge cluster. Custom interior modification of 1971 Chevrolet C-10 Shortbed Fleetside Pick-up Truck.

...this fully loaded gauge cluster.

There will be some redundancy : that being, WATER TEMP in the cluster and pod, OIL PSI in the cluster and a fourth AutoMeter 2 5/8 Pro Comp gauge.

More on the reason for this in the MECHANICAL section of this web site.

NOTE

The original plan for this cluster was to take it to Moe's, a speedo instrument shop I knew of in Los Angeles, CA, to have the speedo re-calibrated and re-faced for 140 MPH and the tach re-calibrated and re-faced for 7000 RPM.

I'm no longer residing in Los Angeles. So what I have decided to do is let you, the potential buyer know, that you could break the speedo and or the tach if you heavy foot the Special on a top end run. The cluster will be sufficient all day long at 90 MPH but the top end potential of the Special will easily 360 the speedo.

In other words, I'm leaving the cluster as is and re-face and re-calibration is on you, the buyer, if you think you will WANT to go more than 90 MPH. Last I checked the fee for this modification was approximately $ 350.00.

Here is a search engine for speedometer and instrument shops, some do custom modifications and some do not. The ones that do have samples of their work, like this :

Hurst Pro-Matic 2 wire harness and park / neutral relays. Custom interior modification of 1971 Chevrolet C-10 Shortbed Fleetside Pick-up Truck.

The Hurst shifter has a switch for start in P or N only and to activate the B / U lighting.

OEM design has 12 ga. wiring for the P / N and 14 ga. for the B/ U.

Rather than run the electrical load through the Hurst switch, I decided it was in the best interest of switch longevity to run the loads through relays.

Shown are the Hurst shifter, the fabricated quick disconnect wire harness and the modification to the OEM harness.

Even though not necessary for the B / U lighting, I am still going to run that load through relays.

The shifter is designed to be removed and installed by disconnecting the wire plug at the shifter, removal of 4 mounting bolts, the shift cable bolt and the shift cable clip. It is easy enough to do, however, the only reason to do so would be to replace the weak link in the Hurst system ; which would be the P / N B / U switch at the shifter. Running the load through relays should result in years of service from the Hurst switch.

This shifter quick disconnect wire harness is placed and secured on top of the Quiet Ride insulation.

Note service access for cab mount bolt.

Poly mounts have already been installed on this truck replacing the OEM rubber, so it is very doubtful that they would need to be replaced. However, the access for the cab mount bolts would just be a matter of removing the carpet and the insulation will remain intact because one would not have to cut it all up to gain access to the bolts if need be.

ABS PLASTIC KICK PANELS WITH 6 1/2 inch 80 watt SPEAKERS


Prep and modification of the ABS plastic kick panel with 6 1/2 inch 80 watt speaker for the 1971 Chevy C-10 pickup interior.

PHOTO 33 : CLICK TO ENLARGE

As you can see in PHOTO 32 the area where the ABS plastic kick panel with speaker is to be placed already has the Quiet Ride Solutions insulation installed ( even the vent door is insulated ) and in keeping with this theme of "over kill" I decided to configure the ABS speaker kick panel with a little extra "vibration resistance" which should push the sound waves more out into the interior of the vehicle.
Felt to the back of the 6 1/2 inch 80 watt speaker is secured to the back of the ABS kick panel.

PHOTO 34 : CLICK TO ENLARGE

The idea is to make the ABS speaker kick panel a separate removable component, so it has quick disconnect speaker leads and its own cardboard back.

NOTE: the speaker is removable from the front, so none of these modifications were really necessary, however, I think these mods will enhance the sound quality and makes for a cleaner installation.

Modifications complete on the ABS plastic kick panel with 6 1/2 inch 80 watt speaker and ready for installation on the 1971 Chevy C-10 pickup interior.

So there we have it, the ABS speaker kick panel "unit" ready to be installed.

Three sheet metal screws and the two vent door handle machine screws secures the ABS speaker kick panel to the cab interior.
