I've worked on fixing at least one of 'em that was done around here back then... Sloppy work to say the least... Not that I'm entirely happy with the swap we did on Rob's rig, but it was light years better than what I "got" to fix.
I'm trying to remember if we had to do anything special with the steering shaft on Rob's rig way back when, but that was so damned long ago that I really can't remember anymore. I really don't recall doing anything other than picking up a rag joint to mate with the steering box he'd picked up, and it was a direct bolt-up. His rig was an '01, and (IIRC) we grabbed a rag joint from an '80s 4Runner.
There are a couple of things that scared me about Rob's rig, and I did half the work on it lol
