Sedan Vs Wagon floor/underbody ??

[unklesam]

Hi,
Just a random thought, I need to go take another look at the Wagon body a boneyard locally has first but just thinking how rotten the bottom of my sons FB is, if the wagon is any good would it be worth cutting the whole floor and sills off at the pillars and swapping in ? sounds a decent sized job but then vs inner and outer sills and floors etc wondering if it might make sense.......
Anyone done anything along these lines before ?

Im not 100% sure but I would bet they are the same from the firewall back to above the diff so it could be done.

that's what I was thinking but I went and took a look again, must have had my rose coloured specs on first time round, there is more rust then tin on the poor old girl.
