It sounds as if you have the somewhat scarce AC Pulley. If so, the two outer unused grooves will be slightly smaller in diameter than the inner fan and PS grooves.

Anyway, if you have the pulley, that is most of the hard part. All you need now will be to decide on the type and location of compressor mount & who will build it and do the 12v conversion. Think you said you already decided the style AC unit you want although, IMHO, unless you routinely have back seat passengers not sure how much need for that second unit. You could make capacity provisions for the possibility though and install it later without too much additional work. Essentially all it would do is "tee" into the existing lines with refrigerant being controlled by a solenoid valve. One additional thing I would do is insulate the floor as best you can with something under the carpet. Several have used the reflective foil type sold in home stores. Not much chance of doing anywhere else without a major tear up. I would see how things check out before changing anything on the radiator, particularly if there is a chance of prior AC.

Finding the pulley, do you know if it's the original motor or did the car have AC at one time? Maybe you have some extra unaccounted holes in front of trunk & screw holes in L fender above blower or if hang-on aftermarket, maybe some in firewall & under dash? How about the fan -- standard 4 blade or is it a 6.
