I already use the A4 compressor and they come serp already, then use a reg GM alternator pulley, GM already has a serp P/S pulley, redrill a chebby W/P pulley, looks like everything would line up. Of course add idlers, the problem I was seeing was the crank pulley. How much deeper of more shallow is the ford crank pulley as compared to the two oringinal V's ? the way I had it figured was just A/C had to be shimmed to bring it in line with everything else?

I've been trying to do this for a couple years... Ill be looking forward to future posts.

What ring are ya talking about? Not quite sure I know what ya mean.
The late 80s chevy stuff all turn the water pump in a counter clockwise direction. The only three water pump pulleys that were equipped with grooves and not smooth were the taurus, crown vic and ford ranger.
The one from the crown vic won me over because the spacing was easily matched when used with the f-150 crank pulley. I tried using the one from the ranger but couldnt match it close enough to any of the other crank pulleys. It would have required too much spacing for my taste. Also tried several different gm crank pulleys but couldnt match that to any of the water pump pulleys. The waterpump pulley pretty much dictated the rest of the system as I didnt want to mess with the spacing of that pulley. Any of the others are a lot easier to manipulate.
I have a bucket of prolly a dozen or more left over pulley from a variety of manufacturers that I used to try multiple combos. Unless I missed something real obvious the combo I have pictured I believe is the most straight forward and easiest approach with the least amount of custom work involved. I like keeping things as simple as possible.
I did try the gm alt serp pulley but in order to line it up with the pow steering pulley, it had to have so many spacers behind it there were no more threads showing to put the nut on. The VW serp pulley fell right in line without additional spacing.

I was at the junkyard today and I think I solve my AC problem with parts from a third gen firebird. gonna mock some stuff up and Ill post some results later.
