Hey Guys,
Please go back and review the last several post in the thread "Quick Pins"(mid Jan 08). There is a post w/picture of a Classic Anchor Bolt Failure. And several posts discussing clevis pins vs quick pins vs shackles.
Grandpap, you may find some useful ideas there, Ok. (Took me several days to remember where those posts were and search them out)
