9 passenger floor pan swap

Looking for leads on info for swapping a third row floor pan from a 9pass into a 6pass 1960 Pontiac. Would the rear pan for 1960 Chevy wagon work?

 

So far I can't see how to do it.. you'd have to have the donor floor and ton of will power

 

Chevy *might* work but the frames are different on the two cars even though the design is similar. So there's a chance it's not exactly the same.

 

I certainly don't think its worth it

 

Chevy is different for sure.. If the floor well in the 9 pass is good I'd restore that car instead.. The gas tanks are diferent in the 6 and 9 passenger wagons too. The one I'm working on is a 9 passenger and I need that rear floor well and a rear bumper.. can you help me out? I'm in Charlotte..
