1967 Monaco Pitman Arm

So, I'm basically rebuilding my steering from the gears out. I've got the box itself and tie rod ends on order. I've also ordered a Pitman and Idler arm from Firm Feel which is fine but I was wondering if anyone has any experience with them from a quality and service standpoint?

It's a huge deal of any sort but I've got a lot of wrenching to do if I'm gonna drive by the end of summer. Don't want to wind up wasting time if a company tends to be lax about things.
