I had an eaton carrier and true track set up with all arp bolts. The ring gear was also wire tied. Anyway it broke 3 of the main cap bolts and put the carrier part way out the cover....Curious on what blew in the 8.5"? Too bad Olds didn't keep the bolt in axles, at least eliminate one failure spot. You must be hitting hard to break the 8.5". I have only blown up the 7.5" in my 88 but my sh*t is slow. I feel confident in the 8.5" Type O in my 70S till I blow it up.
