So I got around to doing a "dry run" and the bolt held to 70 ft-lbs. The only werid thing was after the round of 40, then 70 ft-lbs I redid a round of 70ft-lbs and that bolt turned a bit more than the others to get back to 70ft-lbs again but held fine, but this has me wondering if I should use a stud or the factory bolt.
