1991 Chevy Truck Interior Upgrades

More Work Than It's Worth

With the old interior torn out I realized I had bitten off way more than I could chew.

Ever take on a project that is a great idea but a headache beyond imagination once you are in the midst of it? That happened to me recently when I decided to try my hand at transforming the interior of my Red Sled project '91 Chevy extra cab. When I got this truck it had been sitting outside with a busted window for over a year so the interior was far from perfect. I don't usually mind driving a ratty old truck, so I lived with it for a few years. But then one day I rode in a friend's '95 Chevy, and really liked his modern, curvaceous, clean interior. He had the same body-style truck, but the interior was entirely more modern, so I wondered how hard it would be to update the Sled from the dated early '88-'94 interior to the more appealing '95-'98 style. I asked around and most folks thought it was a good idea, but few had actually done the swap. Then I called a few interior shops and though they agreed it was an interesting idea, none were available to help do the swap in my time frame. I finally surfed the Internet and found a whole bunch of guys that claimed they had done the swap easily in a weekend. I was soon reminded that what's on the Web isn't always true. So I figured I'd do it myself. How hard could it be? I can weld, I can wrench, I can even change tires, so there was no reason I shouldn't be able to tear out some seats, carpet, headliner, and a dash and then replace it all with new stuff. Boy, was I wrong.

Let me state for the record that this conversion in no way increased the off-road ability of my truck, and I should have learned right then and there that doing it was going to be a nightmare. You see if I had simply refurbished the stock dash I'd be driving my truck by now, but I had to get this hair-brained idea that I would swap in a dash that might or (most likely) might not work, and now I have a giant dead truck in my shop that is languishing like a beached whale, and it is nobody's fault but my own. In fact, many of the parts I used worked out great; unfortunately not all the parts I need are available through the aftermarket, and so I'm still looking for more junkyard-fresh parts to finish it. Will it eventually run again? Watch our Web site, www.4wheeloffroad.com, to find out, but here are the major steps to interior redesign on a truck I should have taken to a pro.

Here's how this all started: The interior of the Red Sled had sat with a busted window for over a year, thus the old bench seat had some funky stains, the dash was cracked, and there was no stereo. Plus I really hated the original square dash and late-'80s-style gauges. The headliner was also dropping on my head, the seat controls were busted, and the carpet smelled funny. Pretty normal for any of my personal trucks, but after I rode in a friend's newer version, I decided an interior swap was in the cards for the Sled. I had seen the '95-and-newer curved modern-style dash and since the body style had stayed the same from '88 to '98, I assumed the dash would drop right in.

  • 1. I started by tracking down the new parts. LMC Truck is the complete shop for Chevy truck restoration and they have an excellent catalog of parts for Ford and Chevy trucks from 1947 up to today. However they hadn't done this swap before, so I had to first convince them it could be done and second figure out what parts I needed. I did both based on the hearsay of others that it was an easy swap, and quickly had a plethora of interior parts on the way. I also found a junkyard that had a '97 Suburban with the same red exterior color as my sled but with the more appealing gray interior trim. Since I knew I needed door panels, I got both front doors as well as returning multiple times for other parts. Then it was home to tear out the grungy old interior.

Since LMC had some parts like a new wheel but not the complete column, I dragged those junkyard parts home. I realized that I would also need to cut the firewall mounting brackets off both trucks and swap the new onto the older, which required drilling some spot welds out and welding back in.

There was a grab handle bracket off the passenger side and a hood-release mounting nut off the driver side that needed to be cut out and added to the older truck. It was about this point when I started wondering if simply keeping the older style dash and getting all new replacement parts for it from LMC wouldn't have been a better idea.

  • 7. Before long I came to the realization that the entire wiring harness from the used '97 truck is different from my '91 truck, and I was inundated with wiring nightmares. Luckily I made some calls and found that the dash I had chosen was specific to '95 since it didn't have any airbags. Plus my truck had the engine computer behind the dash on the passenger side where newer versions had it under the hood, except for early '95 trucks. I didn't know if it would work exactly, but I called around looking for a '95 wiring harness with the computer behind the glovebox and the gauge cluster that went with it, all of which should arrive after this goes to print. Watch the Web site for a conclusion to the wiring dilemma.

  • 8. Though I knew the wiring wouldn't have the truck done in time, I moved ahead with other parts like the doors. On the driver side I swapped on the door from the Red '97 Suburban while on the passenger side I had to swap the inner panel since the '97 door was all bashed in. This required swapping the cover panel and an inner support panel, and while the door was apart I replace the drive motors for the electric windows with new LMC units.

  • 9. Next it was time for a new headliner. The LMC version has an ABS plastic backing that helps support the liner and it quickly goes up with some double-sided Velcro (having someone help makes this step easier). Then you just snap the A-pillar molding into place to hold it. Adding the new LMC sunvisors and dome light helped keep the headliner from falling down. New rear panels are no longer available so I will be looking in junkyards for matching panels for the rear as well since mine were cracked and broken. If the old panels had been in better shape or if I could find the correct color panels for the rear, I have some plastic paint, adhesion promoter, and prep made by Color Bond that also came from LMC Truck Parts.

Plus the front offers two deep bottle holders that have trap doors which drop the bottle down into the chill chamber below the armrest. The cool interior has a 6-gallon volume, while a smaller dry chamber is perfect for CDs, sunglasses, and so on. With a draw of 2 to 6.5 amps depending on outside temp, this center console will make the sled the perfect place to chill out. Unfortunately the mounting plate for the Daddy Cool didn't quite fit the curved floor hump of my truck, so a bit of fabricating will be required.

  • 11. Next was the insulation and carpet. Though both are formed to fit the truck floor, neither has holes for the seat brackets and they both had to also be cut to clear the triple stick for my STaK transfer case. Another option I feel now may have been a better idea is the vinyl floor mat from LMC that already had some of the holes marked for cutting, and would repel mud better. I decided to go with a set of Husky Liners for the floors for easy cleaning.

  • 12. Even though the new wiring isn't finished, I was able to stuff the new dash in and test-fit the stereo system I ordered from Crutchfield. Crutchfield, like LMC, has a great catalog and Web site, and the technical service and installation directions are excellent. I worked with them to decide on a Pioneer receiver with AM/FM and CD in addition to an iPod connection and a satellite radio adapter. I'll also be stuffing a new set of Alpine speakers in the doors.

  • 13. In the back of the cab I had two small Kenwood speakers that should have dropped right into the factory sheetmetal openings. However, some previous owner had opened those holes to accept a larger set of noise makers. This will be another spot some sheetmetal will need to be welded in to properly support the new speakers, but the original wiring is easily adapted to the speakers using Crutchfield supplied harness connectors.

  • 14. The old bench seat in the Sled was comfy like an old couch, but also stained like an old couch, smelly like an old couch, and all around old like an old couch. I ordered up the narrowest rear bench from Corbeau in order to still allow rear storage at either side for a duffle bag, recovery tools, or camping gear and sleeping bags, but since the seat needs to be raised up a bit, a mounting bracket with legs will be fabricated.

  • 15. Up front I chose the new Corbeau Baja RS bucket seats with mounting bracket and four-point red harnesses. The seats are comfortable yet supportive and allow driver or passenger to recline for that cool-kid driving style or to take an old guy nap. The suspension seat has side bolsters but they are not extremely tall for ease of access.
