That's not true about the nut Dawg. BTW, that is the GOOD Th350 Converter. The ones with the flat pads that bolt to the flexplate. Not the ones with the bolt lugs. Those are getting rare and harder to find. I've got about 7 of them and sitting on them bitches. Transtar in OKC knows I have them too, every time I call my parts guys he asks if I still have them and offers to buy them. When they offer over $25 each, I'll let 5 of the 7 go.Was gonna swap the torque converters, hit a small bump though, guess it calls for a nylock nut and thread lock to prevent coming loose since it'll be bolted together instead of threaded into the tc?

So here's what you do need. Grade 5 of Grade 8 hardened bolts. Just regular nuts, they don't have to be hardened, and good lock washers, I usually used the split type and NEVER had one come loose. Not even at 7500 rpm on a 12.60 quarter mile heavy truck or 11.90's El Camino with 3000-3500 stall converters.
