WIW - 7-1/4 sure grip

The reality is, they aren't worth "much" and here's why. No one, and I mean NO ONE NOWHERE makes rebuild parts. Period. SO, you're pretty much stuck with "what you got". If you think it's rare to even find one (and it IS) just imagine how much rarer it is to find parts. Yes, the "400 and up" would probably be fitting if parts were available. They aren't.

And yes, people will say "you can make this and that work", but the reality is nobody makes parts. I wouldn't spend 400 on something relying on modifying "something else" to work.
