So I was at the Flea market... no, not eBay, the Palo Alto flea market with Coco... and amidst the heat and trash... I came across these:
the 3/4" shackle was an obvious choice, but the ring is not something I have experience with.. I've seen them on Brenton's truck as well as Chris' Camel Trophy truck... but not sure, other than a pintle hitch, how one would use it. for $4, it was worth finding out... :-)
Thoughts or experience with these?
