I'd like to add power steering to my 86 gl wagon. Which parts are better to buy new (cooler, pump) and which are safe to pull from a parts car? Is there a short list of parts I'll need. I'm guessing I already have rack and pinion and that would not need to be switched out.?

all of it would be good from a donor car, and yes, you will have to replace the steering rack with a power one. it is a bolt on swap if you have the parts from the donor.

 

just a new belt will do for new parts. or better yet new bushings for the steering rack, and tie rod ends

Thanks Miles. Currently I'm looking at a 90 Loyale and an 89 gl for donor cars. When I get into it, I'll post pics and videos.
