Actually the no AC alternator mounting bracket came first in the early '83 models. Later AC was added to 60% of all '83's as an option. Then in '84 AC became a standard add-on. Still the same "Bullet Proof" bracket as issued by Porsche today, and it's shorter 5 rib Serpentine belt. In '85.5 the belt became a 6 rib Serpentine belt - in 5 rib or 6 rib belts the no AC belt is smaller on the diameter than the Plus AC belt. Other parts remain the same on both configurations, adjustment turn-buckle, and so on.

Almost forgot - The AC Delete Alternator sits much lower that if it has AC. So the cooling air ducting is different starting on the Alternator Cooling Ducting back cap. With AC the cap there aims down to pass the ducting around the AC Compressor - Where as the rear cap that is mounted to the back of the alternator on non AC cars, the ducting cap aims down then 90* at the bottom of the Alternator it turns 90* to face the front of the Engine - therefore the old style ducting plan is to have the duct pass very close to the bottom of the Alternator - and does snot dip way down any more to clear the compressor.

Now wasn't that a crock - -
