Hello Sarge, The bed I Had on my AA was eight feet overall, not original Ford, but the actual wood planks were set on a crossways ledge so they were flush with surface, and there was a flat area between the end of the plank and the outside, flat vertical edge of the front and rear crossmember. The end profile of the crossmember, in a word picture, was like a channel on edge with an angle iron between its upper leg and under the end of the wood. Channel like a backwards 'C', and the angle like a backwards 'L' to the left, joined at the top of the 'L" and the left upper corner of the 'C'. I agonized over this for a long time, as all of the original Ford script beds I could find were pretty beat,bent, or rusted. This pressed shape of linear steel stock 'used to be' available at truck truck body building shops for in-shop made flatbeds and shelving, but I couldn't find any at the time and considered fabbing it up from stock.
I DID find that the front crossmember of many trucks often had a manufacturer's script (I saw FORD and DODGE). Front and rear were the same and could be swapped.
I guess you just want the strips, but someone else may use the idea for a truck bed they're making. I also considered taking the rear crossmember off at the fastened (bolts or rivets) corner for straightening and body work, and shortening the sides to let me use these nice stainless strips.
