First I like to thank everyone for there input on my engine question.
As I said me and my son are restoring a 1974 chevy nova and are having a great time doing it, but we have a problem the right hand door is shot.having a hard time finding something local, but i came across a 1974 pontiac ventura doors look the same but are they ?

The interior panel is different but the sheetmetal should be the same.

you could use 68-72 parts as well. they have a vent window frame but otherwise are the same.
