I am going to install the PS pump and steering gear (due to leaking pitman arm). What all is needed? Can I reuse gaskets or seals? What ones do I need to replace? Thanks for any help or advice.

 

You are going to need a 2 or 3 jaw puller to fit on the inside of your pump pulley. These pulleys aren't all that strong so don't pull on outside edge. If you are reusing pump reservoir than you can reuse all o-rings that are needed to join it to your new pump but I think a new pump comes with new o-rings. You'll also need that puller to take pitman arm off of gear shaft. If I haven't forgotten anything major the rest will be basic tools.

 

I forked over the extra money for the snapon pitman arm puller. After fighting that cheap northern tool "tool" and breaking it I think it was well worth it.
