56 Buick Floor in a 57 Wagon

[DCCD]

I have found 2 56 Buick 2 doors that I’m told have decent floors. My 57 Wagon floor is pretty much gone. I’m guessing only 57-58 are the same, but has anybody used a 56 floor to replace a 57 floor or are the measurements way different?

They do not interchange. Buick changed the sheet metal from 56 to 57, to get a 4 inch lower vehicle height. Also, I think the brakes and pedals on the 56 go through the floor, not firewall mounted as on the 57. 
I have a decent, though not complete floor if you’re interested. PM me for more details.
