Has anybody used this alternator bracket kit on a small block with electric water pump?

Forgot to add….this is the weirdest thing I have ever seen.
kit came with 2 fancy headed 3/8 bolts that go through the adjustment rod. Go to put them through each rod end, one will go through, the other won’t.
Good one passes through both ends fine, bad one won’t go through either.
Went to the hardware store, they had the same bolts, fortunately, except, black only, not in stainless. So I bought two so I could at least have both the same.
Both fit fine. Just the one bolt March put in the kit wouldn’t fit.
Not sure what in the heck that bolt was..it looked the same , but had more diameter….metric or something???
Never seen the like. Not ultra impressed with March performance, frankly.
Pay more(US company out of Naples, Florida) and the QC is questionable:wtf:
