What all bolts on from 4th gen to 3rd gen

Hey guys. Gonna have to part out my '94, but I am just curious, what are all the parts that swap over. I know the rear suspention components do, that will be done. Also, the T56, that will be done. What about the seats? What else? Thanks guys! :(

you could use the whole drivetrain. seats I have heard the carpet gas tank, Seat belts,rims,radiator fans,Equhast. Some modifations will be needed to install most of the parts but they should all fit.

Well, I have a "better" motor for the '88, should make more power. The diff I am not gonna swap, only 3.42, plus that 10 bolt junk I broke too many times. Seatbelts would be nice, seats are leather so that's cool, rims won't fit without adapters, so scrap that, exhaust is the same as the other car, but I guess a fair amount of things. Rad fans are better on the LT1, so gonna jack those!!! :D

funnina91SS - when you mention the seat belts from a 4th gen fitting a 3rd gen, will those bolt right in? I may have to search junkyards for a new driver's seatbelt since I broke mine - searching for a 3rd OR 4th gen with a black interior will be easier - hopefully!

thirdgen.org (http://www.thirdgen.org/newdesign/tech/4thgenbelts.shtml) has all kinds of stuff on it that will help you I linked it to the seat belt install page.

The entire interior, panels, dash, seats, everything. LT1 Intake, T56, rear end, wheels.....just about everything...most all of them need minor modifications, but will work. Heck, I've even seen an 86 IROC w/ a 94 front end(hood, fenders, nose) and a T/A spoiler.

BTW: I would be interested in the LT1 intake if you would sell it. Abd the leather seats. Thanx.

I will have to experiment, I guess. I would love to sell you the intake and seats, but gonna keep the LT1 intact and the seats are going in the '88. Thanks for the offer anyway though.

What?? Are you serious about the interior swapping over with minor mods? I have a real hard time believing that considering they are completely different chassis... Anyone have any pictures of this??

I'd love to see these myself!

There's no way the interior trim peices would fit. The car is totally different. Maybe the seats, and possibly the carpet with some mods, but no way on the trim...

and consloe... but It would take alot of work to get the trim pannels(door's) the rest would'nt even work.The dash would really take some serious fabbing up to get it to look good. but I have seen a mustang intero in a early modle car so I guss anything can be done if you spend the time and money.

It isn't a different chassis, it is almost exactly the same. It just uses a different front suspension, and I have seen a new interior swapped into a third gen, so it will work.

I dont have the pics right off hand but I will try and find them. I dont know how extensive the work goes to do it, I say minor, but it just depends on what you consider minor I guess. I get you a link.

There the pics are. Enjoy.

Well, I'll be damned!!! Those peices fit a lot better than I thought they would. However, the fit and finish will not be that great and looks like extensive work is required. I guess anything is possible with a little messaging, but the original post made it sound like it would be a direct bolt in. I'm sure the mounting points are not the same. I wonder how those window pillar molds will fit. Bet they won't. The slant of the new Camaro windshield is much greater than the 3rd gen. I'm sure the rear cargo area would be a tough fit too.

Regarding the chassis, my understanding was that it is a complete new chassis, even though they may have similar dimensions. There were a lot of improvements to the chassis to make it a much stiffer car, so I'm pretty sure they are not the same chassis. If they were, there would be no 4th gen, because the chassis is what makes the car new or not.

Then I guess new Corvettes are C4's not C5's huh? Corvettes used the exact same chassis from 1963 till 1982. Second generation Coevette '63 - '67, third gen Corvettes '68 - '82. So please explain your theory on that.

Martin

I admit to not being an expert on Corvette's, but are you sure they used the same chassis from 63-82? From all that I can read, they always make reference to '68 as being "all-new". I would not consider a car with the same chassis as "all-new". For sure 53-62, 84-96 and 97-current are new chassis. So if '68-82 is in fact a new chassis, that would prove my point.

As with life, there are always exceptions to the rule, and maybe this is one of them (I'll continue to do research until I find the answer, you got me curious now!). But I'm pretty sure 99% of the time, car generations are marked by different chassis designs.

Even if a 4th gen does have the same chassis, it's got an all new motor, body, interior, transmission, etc. Wouldn't that make it a new generation?

New motors, transmissions and body designs are very common during the same generation of a car. Especially nowadays. It seems like every year cars are getting new motors, trannys and body styles. My '99 Cobra has a different engine, trans and body panels than the previous year, yet it's the same generation car.

1963 to 1982 vettes have the same chassis. Same IRS etc. There were improvements along the way but suspension etc is the basically the same.

GM wanted to save $$$ on the 4th Gen's and the 3rd Gen's had been very succssful, so GM did a partial reskin.

Floor pan is the same in a 3rd & 4th Gen. That's why the 4th Gen's are stuck with that hump in the passengers floor board.
Lot's of parts interchange.

Speaking of the "hump" on the passenger side floor, where in the world can I get some floor mats that are molded for that. I know I can go to the Chevy dealer, but that means $$$....I have bough two pairs of floor mats and they have messed up both times.

I got the dash to bolt right in. The door panel is just sitting on the door, not bolted up or anything. The 4th gen dash is actually about 2" skinnier than the 3rd gen dash. I thought it was a little wider when just eye balling it.

Also, the 4th gen dash was about 50-60lbs, the 3rd gen one was probably 20lbs with with everything in it. The 3rd gen dash skeleton weighs nothing really, probably 5lbs.

So the bolt pattern is the same on the dash? Very interesting indeed... What about the bolt pattern on the door panels and center console? If this is such a bolt in, I think I might try it myself. What are you doing about the extra 1" of space on each side of the dash? Or is it even that noticeable?


What did the parts cost you? Where might I source them from? The local junk yards around my area only have the 3rd gen cars, no 4th gens yet.

Bolt pattern on the dash is almost the same. The lowerleft and right dash brackets don't line up, but that can be fixed.
You will need to drill a few holes for the screws that go into the firewall since one lines up but the rest don't, that is an easy job.
I am not going to worry about the 1" gap since it isn't a show car, I am building a road racing/top speed car.
It is a little noticable since you can see the dampening material on the firewall, but black weather stripping will cover that up.
Center console bolts right in, but you need to use a 6 speed shift plate. 3rd gen autos and manuals have the shifter in the same place so the 4th gen auto plate won't work at all without serious modding. I tried this last week and didn't want to hack up the auto plate.

Door panels need to be modded to get on the door as well, I am still in the process of getting them onto the doors.

I got the dash from a member here for $300, console was $125 for my first one, second one I got with a trade, door panels were bought from a guy on thirdgen.org for $75, door/window switches, handles, and trim plate were picked up from a local junkyard.

All of these parts can be purchased from SpeedAutomotive.com for about the same price I paid.
I've dealt with them a few times and I am pleased with thier service.

Nice work Zepher! What kind of top speeds are you expecting? Where do you find out?

Thanks, I am going for 200+. Bonneville is one place I want to run. I also want to try the standing mile run at Maxton.
