1950 rear of bed
 

Does anyone have a detailed drawing or good clear picture of what a 1950 F-1 bed rear looks like without the wood? PO kinda hacked away at it

I have a few pics in one of my old albums, they may help a little? Here is a link. (ALBUM #2) NEW BED FLOOR by underthebridgejim | Ford-Trucks.com

Maybe this will help?

Which '50 bed are we talking about, early or late? Early built trucks have the raised panel sides which is a totally different structure underneath than the later flat sided beds.

Good point Wayne, My truck is the early 50, steel sheet over wood sub floor, and tailgate that has chain hook loops inside the upper roll.

My truck is the early style

Moose, I apologize for hijacking your thread but a point has been made and I'd like to have it clarified.
If I understand correctly, the late "50" beds, without the ribbing, do not require the wood frame spacers/levelers. The bed actually sits on a straight, as opposed to axle humped, truck frame?
