OK, so now that I've identified my burly H-072 rear in my '65 3/4 and found a 3.90 gear for the paltry sum of $468, I gots to know: Does anybody out there have a 60-66 3/4 with an original 12 bolt? Did they come with these? Maybe I'm just an unlucky one that bought a C20 with this odd, fat, round Eaton? Looking at the LMC catalog, all they show is a 10 bolt for the 1/2 tons and 12 bolt for the 3/4. What I'm gettin' at is I don't wanna fabricate. My truck is my daily driver so the less involved in the swap the better. Finding something original that gears cost only $200 seems ideal situation.
