the shock bolt in the help section? not sure how it would work. have not investigated it yet. i think i have another one like it in my pile somewhere. what say you? tia.
I have used the replacement stud you weld in but now I would just machine one up on the lathe. I got to the point where I just heat the nut with a torch and have never broke one since I started doing that. Use plenty of anti-seize when you put it back together.
