Thanks for input.
I will definitely pull cover and take a look at rear. Will also test for Posi again to be 100% sure in neutral (only 99% sure last test in N), so will verify.
Would like to know what 'OTOH' and 'NAPCO' mean, sorry I am an old guy and have been immersed in my 1940 VC1 pickup restoration the last couple of years and not as familiar with the 1950's vintage chevy's or computer lingo. Do however know what OMG means since my daughter says it daily.
Will provide pictures of Truck tonight. Bought within the last month so in process of degreasing, changing fluids, fixing some electrical issues (done), brakes, gathering info and ordering knick knacks (hoses, belts, chanin protectors, etc). In process of letting Marvel Mystery oil work on the cylinders, so have not tried to turn it over yet..so cannot at this time assess things such as does it run, does clutch work, does tranny work, etc.
Story is that was parked 4 years ago when brakes went out, and that ran/operated great till then (?). Has 160k miles on it. Have resisted urge to replace differential fluid till I do some more digging, may need 4 oz additive. Will take off back plate with buddy of mine who has some experience assessing these older trucks before do anything.
Is it hard to find a 3.92 DANA on one of these trucks, anybody heard of a truck like mine out there? I have not run across one yet.
