I think I know what you are talking about. In fact, I think you just explained what this impossibly out-of-place looking BOLT is doing sticking out of the case, mid-way up the right side. I wonder if, throughout the years, someone boogered up the fill plug threads, drilled it out, and retapped some humongo threads and stuck a jumbo sized (1" diameter) bolt in the place. I thought it might be used for wrapping a chain onto the case to lift it, and didn't bother with it. You never know what has been rigged up on these old trucks over the last 50 years. I'll fiddle with uber-bolt tonight and see if I can't coax it out of there. Does the fill plug point somewhat at the passenger side rear tire? This bolt is angled so that it does. It definitely does not point straight out the side of the truck, pointing under the frame under the passenger door.
Thanks for the info.
Bill
