54 chevy vs 54 poncho interchange

I'm looking at buying some 54 pontiac cheifton parts for my 54 chevy 210. The parts are door parts, door gl***, window regulators, wing windows, door relays and the garnish. I'm guessing by looking at both cars, that they share alot of parts, but does anyone know if these parts will interchange? Both cars are 2 door posts and are both 53-54.

 

I do remember when the Junk Yards (before the organized stock catalog days) had both bodies for sale. With the exception on the chrome and exterior adornments the doors ( 2 dr post coupe; 4 door sedan; two door hardtops and convertibles were in some cases interchangeable. BUT... remember Pontiac (like Olds) had two body sizes. The smaller of the Pontiac's would interchange with the Chevy's. The Chieftan was the smaller Pontiac body.
