Im putting a 8.75 in a 4 door. I have a driveshaft from a 2 door. Are they the same?

The donor was a 73 plymouth the car im working on is a 72 dodge.

I don't believe so Chris. Floorpans and wheelbases are longer IIRC.

I get conflicting info everywhere.. lol

I think "coupe" means a duster/demon..

This chart says they are the same wheelbase.
http://www.valiant.org/dart/1972.html

They don't have the same chart for plymouth..I kinda remember reading that there was a slight wheelbase differance between dodge and plymouth.. but i could be thinking of satellite vs coronet or something :-/

I guess the only way to find out is to just try and bolt in the driveshaft and see what happens.

What plymouth? A Scamp would be the same as a Dart 2/4 door as long as it's not a Dart Sport or Demon

if the wheelbase and tranny are the same then yes....

but a duster to 4 door valiant, no, the valiant will be 3" longer.

from a 904 to a 727, no, the 727 DS will be shorter

4 door valiant and Dusters are both 108" WB. The 2 door Scamp is the one in the Valiant line with a 111" WB.

Sorry Patrick, how does a 74 model year fit the OP's question?

I answered your statement based on the OP's request. No biggie.
