Wow, Just revisiting this... I just finished the intermediate shaft bushing. Not terrible, but a lot of disassembly for access. It's only been 3 years?!! Wow. I did find all twelve ball bearing in the pan and was able to scavenge a vacuum pump and rollercoaster cam off my parts car. They were pretty serviceable, I may spring for a rebuilt pump and new cam if everything else seems ok after a few thousand miles. On to a pinion seal & rebuilding the injectors!
