I am planning a 20v (Blacktop) swap into an '88 aw11, and wish to keep it air conditioned. Idling in summer traffic @ 40+ C the cabin heats up fast.

I can't find a definite answer to the following questions on the web :

Which a/c compressor to use - aw11 or blacktop ?
I assume the aw11 compressor is smaller=better, but is it good for 8k rpm, or did they change the pulley ratio ?
Same questions re alternator ?

If using the aw11 compressor / alternator / ac, which mounts should I use ?
Do the pulleys line up (one web site says not) ?
(It probably depends on which mounting brackets I use).

Sorry if these are noob questions, but pulleys 1-2 mm out of line are easy to overlook, and I just got my a/c compressor overhauled, so I want to keep it.
