[QUOTE=John V.;5834543]Dick, not sure I agree or else I am misunderstanding what you are saying.

The '64 pulley set-up for A/C used a specific Balancer Assembly that was always 2 groove. Two different groove dias. were employed.

Likewise, the WP pulley was 2 groove and also employed 2 different groove dias. when e/w A/C.

I'm not aware of a '64 set-up that used a 3rd pulley for A/C.

John I think the mention of a 3rd pulley was really a 2nd rear most pulley. The a/c crank pulley used a 4 piece assembly which included the damper, a single pulley and the rear most single pulley along with the crank snout This was serviced only as an assembly. No individual pulleys, damper or snout were available. As yes, the pulleys were different size diameter as you mentioned. Just adding the single rear most pulley if you can find one, might help but those darn Pontiacs have year and use specific pulleys and can really be a problem mixing and matching. Adding an 1/8 inch of the rear pulley will push everything else out of line.

W.E., perhaps that is what Dick was thinking, not a production arrangement either way. But thanks for the refresher describing the pulleys on the '64 A/C Balancer Assembly, seem to recall that was discussed once before. Never had one and forgot that the 2 grooves were created by 2 separate pulleys for the A/C Balancer.

The non-A/C Balancer was likewise only serviced as a complete assembly, I believe it used the same weight ring and hub as the A/C balancer. The two grooves were same dia. and used a single pulley, not separate as on the A/C Balancer, see pix of my disassembled Balancer Assembly.

I gather it would be physically possible to add the 2nd rearmost pulley from an A/C Balancer to the two groove pulley on the non-A/C Balancer to create 3 grooves.

But it sounds like that would be a Frankenstein creation that likely won't align with HALFWAY's existing Alt pulley and/or his PS pulley.

HALFWAY, hopefully the RA RESTO PS pulley will do the trick and free up your front crank and WP groove to drive the compressor, assuming you can get the compressor pulley to align with that groove.

Let us know how it works out.
