(Not the right pump or pulley for the vette) but ignoring that, is that pulley dished like the cast ones are? Can't see it in the top photo there. And the bottom photo is a different style again with the pressed on pulley so it might be apples and oranges

Each of these set of pulleys were new in bags. Each said 69-70 BB Corvette. The bottom picture is one offline and the pulley much closer to the pump itself. Possible the ps pump is just not corvette right?
AFAIK, the vette all used the can and tube style up to 74 (75?)
and then switched to the porkchop style like you show. but it might have been the replacement one since they were more common
That said, I believe they were the same dimensional to the mount and pulley
And when I look at it I thought the alt pulley was wrong since it should have a big space before the groove (like a 2 groove one missing the first groove)
But I think I'll step away and let the 69 people help as it might not be the same as I think

I appreciate the input. I'm learning and in no way insinuating any ill will. Thank for the info. That pic you posted. Is that stock stuff? I mean the pulleys? Weird alternator. And yes, my alternator pulley may be wrong. I had this alternator just sitting around the shop and it fit.
Everything else there is stock except the alt which is a cs144 I swapped in, still using the proper fan and pulley. But again for a 72 BB
I "thought" they all used the same pulley on the ps and alt but of course things changed and I'm only really sure about what mine is. Best to check the AIM
Regardless, you need to get the pulleys to align so check where they go to compared to the crank pulley and go from there

The two pulleys in your pic are different.....one is held on by a nut and the other pressed on.....and you have to have the correct corresponding pump of course. Pretty sure this is the discrepancy. The later ones are press on.....like for a 74'.
