Yeah, don't confuse this axle with the true "10 bolt". BIG difference. mugsy--as far as i know, this was the only axle used in 3/4 ton and 1 ton trucks, at least 60-66, and, according to my 60 shop manual, this axle was "used on all 3/4 and 1 ton trucks". As far a later years, I can't say that i've ever heard of a stock 12 bolt in a 3/4 ton. I just don't think they're strong enough to hold up to what some people would try to put them through. I have heard of a few 14 bolts that came in 1/2 ton trucks with 6 lugs, but those are few and far between. Anybody else?
