If you are the guy with the white double cab, I still think your truck is nice! For that rig, power steering will be a great option! The kit you are looking at is based on a V-8 engine. If you have a V-8 then with that kit you'd be good to go. If you have one of the sixes, you'll have to find a 6 based kit or a set of brackets. The Moderator of the '60 - '66 group makes them so you could contact him. Either way, its a pretty easy swap with little to no adjustment.
Best Wishes,
