Bed Floor

[Mister laugh]

Right now I have a wood floor in my 70. The wood has been replaced with pressure treated decking, the metal strips are all rusty, and what i think the worst part is is the inned bedsides where it meets bolts the the floor is all rotted out in some spots. I'm not entirely attached to the wood bled floor, and if i fix this at all this year need to do it on a reasonable budget. Is it possible to graft a 73-87 metal bed floor in? The wheel wells are wider in the 67-72s so i dont see a problem there, and other spots i may run into? And before everyone tells me just to find a new bed, they dont seem to grow on trees here like they do in other areas. 73-87 beds are howerver a dime a dozen especially with the bedsides rotted out and all i need is the floor.
