Will 4 door armrest work on 2 doors? 1970 Olds Cutlass Supreme.I found some perfect 4 door ones of course!

 

You should be so lucky. According to the GM Parts manual these are Group 14.686 and the armrests are listed as the same part number from 1969 = 1972. LH 8769927 RH 8769926. Models this applies to are both regular coupes, CS coupes and both HT and pillared sedans.

If the armrests are the wrong color you can also clean/degrease them and either dye them or paint with SEM.

 

If the price is right you might snag them anyways. You can always swap them with someone restoring a wagon, which is much more common that fixing up 4 doors.
