Floorboard help

[dumbfarmboy]

Got the truck home today, took off the bed and the frame actually looks pretty good. That's the good news. After some poking and prodding I decided to take the cab off of the frame as well...I was told that I didn't need to worry about cab mount rubber since it was all good.....LOL...in reality there was no rubber on the truck...completely gone,
I Cleaned up as much around the cab as I could before starting to cut metal....now I realize I need a complete floorbard including the rear cab mount support. I have new cab corners but I am in trouble here guys. Any ideas on where I can get a floorboard? I dont need the seat support since I am going to put bucket seats in. Got the cab up on sawhorses so I guess I am ready to start rebuilding.
