Jim, maybe you could find some 'clip on' type guards??? (slide over rim, like bernie said, and 'hook on'???)
there is a site that advertises on here that would probably have them. Cobra Accessories???
Now if you have some you're 'stuck with' then maybe you can rig it in a way that clamps onto the rim. Good luck!
Bernie and I go way back, and one of these days we'll have him down for a good ol fashioned Texas round up!
He's known Jay and several of the Texas group a lot longer than he's known me. He's an honorary Texan.
Bernie, I'd love to have you come visit! Just let me know.....
We're still hoping to make it down your way sometime. But not this summer.....
have fun at Knott's.
