1937 Ford Tudor Seat mounts?

[37slantback]

I had the floor replaced in my 37 and now realize that any brackets or braces that the seat would have bolted into are long gone. I looked in my EV8 37 Restoration book but can not find what would have been on the underside of the 37 floor that the front seat would have bolted to. Does anyone have a picture or description? I can fab something but wanted to know what would have come from the factory. Macs has 38-39 "floor stiffeners". Is that what the 37 had only with different dimensions?
