I need clarification on the number of notched cross sills for a 1947 AD 3100.
My box had the incorrect cross sills and I suspect even the incorrect box. The under frame gas tank nozzle seems to have been carved out to fit the filler tube.
Sooooooo, I want to be sure I have the correct information for my rebuild. Conflicting info has me understanding the half ton had only one notched cross sill for over the gas tank. The long bed option and the bed of the 3/4 ton from 1947 BOTH required TWO notched cross sill? I’ve ordered one notched sill but now question whether or not I may require TWO.

Can anyone help me out on this so I don’t make a stupid error? Don’t want to appear even more silly than I am! ;-)
