While my first choice would be an Eaton Posi, because they're rebuildable, OEM, and bombproof -- I put an Auburn posi in the 12-Bolt Corp 3.73 rearend on my '67 K/10 Suburban. let it sit for 10 years after the sub's engine fire. changed out the rear brake sets for 11-1/2'' [drums w/ finns] and 2-1/2'' brake shoes to match my '71 K/1500 Jimmy.
When that truck's factory 12-Bolt w/ factory Eaton posi blew out. I cannibalized the Sub's whole rear assembly for the Jimmy. Nine years later still rockin'n' rollin' on that Auburn posi.
[Now if I only had the bread to bring back the Suburban....?]
