help platform interchangeable parts
 

I have a 65 falcon ranchero with 289 and c4.
I need to know if the mustang and falcon have intercahngeable parts for like the frame, floorpans, rear end, suspension, and other stuff.
I would appreciate any help on the subject thanx

I have a 64 Falcon sedan that I just rebuilt the suspension on last year. I used a full Mustang front end rebuild kit from Canadian Mustangs and their 4 1/2 leaf rear springs and everthing fit fine. The only thing I noticed is the rear end seems to be bouncy.
