Checking Sprag

Only way to know for sure is to tear it down and look. Cheaper bolt ins can flip the spring retainer thingies too. I’d look if it were me.

Yep
Even a bolt in sprag can roll in situations such as axle/ rear end breakage.
Always need to check it in such situations, the stock drum can turn 15k rpm and at such rpm is a ticking time bomb. Billet drum or aluminum drum is good insurance in a 727
