and the grind marks ? </div></div>

That's 100% real. I am going to assume that the &quot;grind&quot; marks are just from a tool adjusting the alternator when it's in place. Corvette HP alternators from this era all had &quot;strange&quot; looking stamps.

Here is a 1970 LS5 Corvette stamp for comparison.

I've owned two of these alternators in the past and both of them had a small pulley on them.
