Hi All,

I am hoping someone here can help me out...

The box on my 1939 P/U rests on boards which are bolted to the frame. In between the boards and the frame, the truck uses Wooden cross members which raise the box up off the frame at the front and at the rear.

I believe carriage bolts, about 8" long, are used to hold this all together. They appear to be 7/16" diameter (hard to say as they are pretty much non-existent now).

My problem is that I have searched high and low for 7/16" x 8" carriage bolts and have had no luck in sourcing them. This seems strange as they are available in 3/8" diameter and 1/2" diameter (the guy at the fastener store says that nobody uses 7/16").

I would not feel safe holding the bed in place with 3/16" and 1/2" is too big for the holes in the steel part of the frame.

Does anybody know where I can get these?

thanks,
George
