I work on a lot of field cars and most of the floor boards are gone when I get them.
I make all of my floor boards and I try to get them to look like factory, unless it is a hot rod and they want a different design or the floor is missing.
To be able to accomplish this I use a different method, most bead rollers do not have a big enough throat. So I use a pullmax machine. The one I have was made in the 50's and weighs about 2500 lbs..
The floor board is a '40 Ford coupe that I work on when I need a break from the bird. The only piece that was saved from the '40 is the drive shaft tunnel and the master cylinder filler opening. Everything else was pretty much gone.
