Great. Differential guys are usually pretty good.
I had a 12-Bolt rearend rebuilt at Tucson Differential for my '67 K/10 Suburban in 1997. New Moser axles, Bearings, shims, new Auburn Posi. Suburban went down in '99 due to an engine fire. I parked it. The factory 12-Bolt Eaton Posi rear under my '71 Jimmy lunched in 2010. I was broke, so we cannibalized the Sub's rear and put it under the Jimmy. Still running good.
My '68 C/10 Stepside got T-Boned last month, crunching a 12-Bolt diff with Eaton Posi. I bought a '65 MY 12-Bolt rear from a fellow K/5 collector, $200 for the core. I took the core to Tucson Diff. They totally rebuilt it with new axles, bearings, shims, 3.73 ring and pinion etc. for slightly over $1200. The manager had worked there 25 years ago, but we couldn't remember if he worked on the Auburn job. Anyway they still do good work. And adjusted for inflation, it's pretty cheap.
