I am in need of a center floor pan for a 1939 Ford convertible coupe. This is the sheetmetal piece that fits between the two wooden floorboards and fits over the transmission.
I will tell you they are a bit tough to find in decent shape but do show up on occasion on eBay.
Do not let anyone convince you that all you have to do is cut a hole in a '40 pan for the (floor) shift lever. The 40 pan will NOT fit the 39 opening.
I bought the 40 trans cover from Carpenter but to make it fit I added metal to it. 40 is shorter but the mod can be done so it is hard to tell it was done.
