Shaft broke because the stud broke. I'm not sure what grade a Dorman stud is but I don't use them for anything significant. You can buy individual studs directly from ARP. Tell them what size you want. My paired T&D's had 2 studs on each mounting bridge that I thought should be longer. Bought new ones from ARP, reasonable. Doug
I agree the stud went first... not sure if it was loose or just weak
