A few questions on a power steering gearbox.

[ghostvbhc]

Will a 1978 C10 power steering gearbox fit in a 1969 chevy C10 and if not, what modifications would I have to do it to have it fit correctly? Also, would a GM power steering gearbox from 1982-95 work for a 1969 chevy C10? And, would a power steering gearbox from a 1983 chevy pickup (4x4) work with it? I'm asking because the last thing we need is a power steering gearbox for the truck to have power steering and we found a few on craigslist, but we don't wanna buy it and then have it not work for the truck.
