Noisy starter

[Jeepster376]

So I replaced my starter with a Napa rebuilt, just because my old one would occasionally struggle a bit. The old one had a couple thin shims so I installed the new one with the same shims. When I cranked it, it made horrible loud noises. So I removed the shims and now it's better but it's still very loud and doesn't sound good. I was better off with my old one that is now off in core charge land.


Now there is 153 tooth and 168 tooth flywheels, and corresponding starters. Is one the straight and one angled bolts? I have the angled bolts. Is it possible to have the wrong starter? Or is the starter I got a POS? I don't know if I should return this one, for another of the same, or if I need something different.
