does anyone know the demension's of the smaller peices that are on the bottom of box front and back???
Do you mean the flat filler pieces under the stake pockets on each side? I can measure them tomorrow for you.
I have an F 1, 52. Sorry could you be more specific? Box, meaning bed? I know those trucks pretty well, sorry, don't know what you mean.
Let's see who measures first! It's supposed to be 11 degrees here in the morning. Got to let those pocket drain or they'll rust. I don't think mine are filled at all.
My truck is a 48, but the bed came off a later 50 1/2 to 52, the front pockets have no filler piece,the back both have filler pieces with a drain hole in it. The pocket measures 2in.x2in.
Mackhils makes reproduction pickup beds and parts. According to their catalog, the 48-late 50 bed did not have lower side plates. The late 50-52 bed did have lower side plates. Front to back the late 50-52 bed lower front plate is 17-1/2 inches long and the rear lower plate is 5-1/2 inches long. These dimensions include the stake pocket. You can tell if your bed is an early bed if it has a reveal on the side. The late 50-52 bed sides are flat. Mackhils does not show these flat plates as available parts, just as part of the bed side. Their website is www.mackhils.com. I hope this helps.
