1970-72 A-body?

I'm wondering if a 4 door frame is the same as a 2 door. Deck filler panel, front and back glass, rocker panels and roof from the pillars to just above the sail panels and drive shaft? I assume the front clip is completely interchangeable along with the cowl panel metal, firewall metal, steering column, dash components and pad, a/c hoses and components and rear end. Basically can a 4 door be turned into a 2 door?

 

4 door is a longer wheel base frame

 

Only the dash forward is the same.

 

....with the exception of the rear bumper & tail lights, trunk lid, trunk floor, qtr extensions, window & trim, gas tank, rear dif....

 

How about the deck panel between the rear window and the deck lid?

 

I have not checked but I can;t see why it wouldnt be

 

Yes you need the doors,door post ,and rear qtrs I've done it to a chevelle ..
