On my 69 step I have Cal-Trac bars and the overload leaf hits the forward rod. I'm going to pull the overload leaf since it will serve no purpose in the future. So, I'm going to order new center pins and I took the extra set of springs I had away.
Anybody know the diameter of the pin so I don't order the wrong one?

3/8" is what I'm thinking. But 5/16" and 7/16" also common...
