    any 3/4 or 1ton will work and get all the p/s pump stuff with lines. but make sure you have dubble 45 flare lines to match up to your old style box. the 80s went oring style. but if planing crossover great time to upgrade to 2x4 box to match.

    and just basic bolt on and blead both systems proporly. only thing needed was remove brake pedel bracket and pop out the 2 studs from the vac system and bolt on the hydro stuff.

    I used a half ton hydroboost setup...You can "T" the return lines and use your old pump, but some people have had issues doing that, including myself. I ordered a reman HB pump, and the two return line nipples improved the performance of my braking.

    The pedal assembly I used (off a HB truck) had a different mount position for the master cylinder rod, and the rod was a different length than the vacuum setup. I recommend getting the pedal and rod when you get the HB unit. Some have used their old pedals, without problems, but I bought the whole thing while I was at the junkyard - I told him from the pedal to the pump.
