parting out 74 dart

Im still at odds on the rear seat fitting. Some say yes it will some say no. You wouldnt happen to have a good seat from a 2dr do you. I'm still working on the right answer if the 4dr one will work or not.

If they are the same year model, the rear seat from a 4 door will fit in a 2 door. The seat bottom will leave viods on the sides at the rear door opening areas.
The rear seat bottom from a 2 door wont fit in a 4 door. It's too wide.
Hope that makes sense.
