Ok So I am new to this forum and have a couple of questions. I have a '72 Olds Cutlass Supreme, 2door, long time work in progress. I recently came across a 72 Cutlass Supreme 4 door. Question 1. Will the entire front end interchange with my 2 door? how much of the Backend? Just bumpers Lights etc.? Trunk lid? Glass? Also what is the average cost of a non running intact 4 door cutlass supreme these days?. Thanks in advance!

 

The entire front end will interchange. I don't think the glass will and I doubt the bumper will. Hard to say what a non=running 4 door would be worth without pictures. It would depend on amount of rust and if the engine turns over and what other savable parts are on the car.

 

The front end sheet metal will interchange, lots of suspension parts, etc. If the 4 door is cheap enough and you have room and neighbors who won’t complain (or live 10 miles northeast of nowhere) but it just to have. I really wish I had a place to stash a parts car. It sucks having to either drive an hour to see people who do hoard this stuff, or mail order stuff.

 

Unlike newer cars, the four doors and wagons were identical to the 2drs from the dashboard forward. Note that there is a 4" difference in wheelbase, so frame, floorpans, driveshaft, etc are all different. Rear bumper and gas tank are the same. And of course those four doors came with a "convertible" trunklid.

 

If the more door is clean consider not chopping it up. Buy it and drive it.
Cheap rust-free more doors are gaining in price and popularity. I wouldn't mind having one for a daily. I'm still kickin my *** when I passed on a mint granny car 68 F85 freshly hauled into a Sacramento junkyard 35-40 years ago. $300 would have bought it. When I say clean I mean spotless. Shame...just sayin.

 

Joe thanks for that info. I had no idea about the deck lid. Is the rear window the same?

 

A 4 door glass is not a convertible glass, if that's what you meant.

 

I was just thinking that the rear glass (back window) in a four door is the same as a two door right?

 

That I don't know. I think there's angle differences, so it may well be close but different.

 

Not even close.

 

For 68-72, Sport Coupe and Holiday Coupe rear windows are the same
Supreme notchback (4257 body) is unique to that body
Holiday and Town Sedans are the same
