35/36 Pickup Seat Base

[OldGold360]

Is there a factory Ford blueprint for the plywood seat base for 1935 or 1936 pickups? Don Rogers might be the guy that would have one. I’m planning to make a handful of these plywood seat bases using a CNC router but I only have pictures to go off of for dimensions. I do have original seat springs but if I make some, I want to make them correct. I did find a CAD drawing someone drew on a later year base but some things seem a bit of or dimensions missing and I would like to find a copy of the Ford blueprint if it exists. I have the floorboard blueprint, and plan to make a handful of these as well, but just a little stuck not being able to find more info or an actual plywood seat base that I can use for specs.

I have six sheets of nice 5/8” plywood and plan to do a run of the floorboards and the seat bases, complete with the metal adjustment plates and turn buttons, if anyone is interested. I’ve attached pictures of what I have so far. The floorboard is finalized, but still uncertain on the seat base.

Thanks!
