Default C3 Door Compatibility?

Hello,

My 1974 Corvette has completely rusted out and destroyed doors. I found a set of doors off of a 1978-82 car for a good price. Would these doors work on my car? I know the door panel is different. Could I use all of my 1974 hardware on them like the locks and power window parts, and use '74 door panels on it instead of the later style?

Thanks,
Will

I had 2 81's and the locks are different as far as in the 81's the **** isn't that cool twist thing but it pulls and pushes in the end of the arm rest/door pull,
If you are handy I would think the rest would swap over and you could do the locks to fit your year but I do not know if the door shape itself changed....

If you have complete 74 doors, you can swap the internals and linkages over to the newer doors. Mounting the handle assembly will require the use of nuts rather then the nuts welded on the door like the 74. You will also have to remove the brackets for the later door to fit your older panels. All in all it is not a big deal.

I had both sets of doors and managed to configure the newer doors for use with older door panels without swapping the internals. It required custom fabbing a bracket for the reverse pull/push handle mechanism and mounting the handle assembly.

Ok so the biggest thing is the locks. I definitely want to keep my car all original in that sense, but it seems with minor modifications (I do have the doors on my car complete minus some missing sheet metal )

I think these doors might be worth the purchase if it's that simple.

I agree, and especially because they seem more prone to rust then the rest of the car, as surprising as that might sound. My doors are *shot* while the rest of the car has rust, it is in pretty good shape. Birdcage is solid, frame solid, just those door frames are bad. I think it is because they are the only body sheet metal thickness metal on the car. Just like a 70's steel car body rusts, our doors rust. That's my $.02 though.

If anyone has any insight into the compatibility or rust, feel free to chime in!

Do only C-3's have a metal inner door? I think C-2's have both outer and inner panels made of fiberglass. I sure wish someone made 68 doors. Lou.

Loup68. You are right-the entire door on c-2's was fiberglass. Probably not as strong and safe as the steel on c-3's

In the early 1980's here in Los Angeles, I was at a local body shop and they had a C3 that someone had bought in Florida and brought to Los Angeles. The body shop owner showed me that the steel door pans on this C3 were practically completely disintegrated by rust from the humid, and probably, salty air environment you can find in Florida.

I'd think that salvage doors are pretty available...have you tried J&D Corvette in Bellflower, Ca. With a Ca salvage car, you're more likely to find less corrosion...I've bought a bunch of salvage parts..California and Arizona parts are more likely to be not corrosion damaged.
