    I'm pretty sure the 85 will not fit the 76 the frames are too different. If I'm wrong someone will correct me I'm sure /forums/images/graemlins/grin.gif

    I'm thinking the box will bolt up, the difference is the threads on the box for the fluid lines, thats why the part # difference. You can swap the fitting on the back of the PS pump with a newer one, so you can run the newer hoses.

    The fitting on the newer ones is like the AC connections, with an o-ring, while the "old" ones were just flared.

    I guarantee someone knows for sure if it just bolts up, it's just too early in the morning /forums/images/graemlins/smile.gif

    in 79 through 80 they changed that threads on the pump and the gearbox if you change the gearbox you will have to change the pump and hoses aswell i think they will bolt up the same but dont quote me on that. they look the same with exception if the fittings. i gust payed 50 for a pre 79 pump, pbracket, pullys and belts because i didnt have any of them (i think i payed to much but o well) any ways hope that helps /forums/images/graemlins/rotfl.gif

    The fitting for the pressure hose on the back of the pump unthreads. You don't have to change the pump itself, just get the fitting of the correct style and swap it. Then you can run the newer hose with the new gear box.

    I changed mine from manual to power steering a year ago mine is a 77 and I went with a 1980 box and pump the only change is flared fittings to o-ring on the hoses,The threds also changed.the pump I got had the flared so I changed the valve in the back of the pump to match the o- ring hoses. /forums/images/graemlins/k5.gif /forums/images/graemlins/usaflag.gif mike
