Any suggestions for a place to get GOOD / HIGH QUALITY heavy duty u-bolts? I want 3/4" dia, 8 grade stuff (or better) bent to my specs. I had a new "grade 8" set that I just tried to install but 2 of them stripped out. I put them on with a 1/2 ratchet (not air gun) and realized I needed to take them off to change something and the damn things were galled(?) in the nuts. These things might have been tightened to 75ftlbs.. I'm going to contact the guy I bought them from but I just don't know if I trust his source now.
