I'd like to hear about this myself. I'm looking for a place to get the injection pump timing set on my '92, and I'd rather not pay the $90-something/hour shop rate that Cummins charges for this if I can help it.
I found two possibilities for what I wanted:
Al's Diesel Works
Advanced Diesel Service
However I haven't been able to get my truck in to either one.
I'd love to hear any suggestions from people who've had good experiences with shops in or around Anchorage.
