my dad wants to put power steering on his 68 chevy c10 pickup he is 68 and it's hard to drive for him now. both of us are pretty handy around the shop we just need a little guidence on what parts will fit or could be modified fairly easily to convert it. any guidence would be greatly appreciated.

You'll need the following parts to make it work.
at least a 2 groove pully, Power steering pump with brackets, hoses and a steering gear.

You can use the 73 up gears but you have to modify the frame just a hair to accept the new gear. Some have reported not having to anything but simply bolt the new gear on though.

I have pump, brackets, belt and pulleys if you need.
PM me if interested. I could come up with a gear too but the shipping wouldn't make it worth while.
