We usually only replace the springs and rollers,about $25.We do use the bolt in overrunning clutch if there is damage to the the inner or outer support rings.The bolts that hold the clutch(sprag) in place do nothing to stop the it from "exploding" If it is going to happen(usually from abuse or incorrect use or other drive line breakage)The new A&A and other "Super Sprages" with more springs and rollers may increase the life of the unit.If your set on replacing it,I would recommend A&A,Rick is a great guy and supports the site and Mopar racers.
