    I just recently bought a '77 GMC 1/2 ton p/u with a 400 and i was wondering if anyone could tell me what axles it came with stock and any special specs it might have stock.

    <font color=blue>Your truck came with a 12 bolt rear and a dana 44 front. More than likely you have 3.42 or 3.73 gears, but to be sure you have to check the gear ratio code inside the glove box. The codes are on this site somewhere, I just forget where.</font color=blue>

    Big gray has it nailed, but make sure you positively ID them, stuff that old could be swapped around really easily.
