Alternator line up

by the way, it seems odd that the grooves on the aluminum pulleys are spaced so far apart (1/4 inch?), when the factory pulley you are trying to align with they are butted right up against each other. Does the pulley manufacturer offer to revised alternator pulley with the same configuration? how far apart are the centers of the grooves on the aluminum pulleys? I think that the factory distance on a double groove pulley is 1/2 inch.

It does come with a aluminum pulley...I didn't install it because the factory looks so far off..it doesn't appear that changing it would make a difference...Would a newer alternator change this line up? That is the original slanty alt ..I guess I can get a napa 360 alternator post 1970 and see if that changes anything. As far as using stock equipment I have it...It didn't change the line up issue with either sets of pulleys / brackets..Which leads me to believe the earlier alt was different..I was looking for conformation of this.
