Re: Is adding air conditioning an unobtainable myth?

It's hard to tell without seeing it in relation to the vibration damper but at first glance, that appears to be a power steering pulley--although it does have a wide space before the groove. If a PS, it will be the same diameter as the vibration damper fan pulley. The AC pulley is spaced out slightly and almost 1" diameter less than the others. Here is a picture of the factory pulley having the PS and AC grooves on the same casting. There is a separate single AC pulley also available which works with the existing PS pulley. I borrowed a picture of Jack Nordstroms repro to show what that looks like. The PS pulley will work for AC and many have used them although compressor RPM will be higher than optimal. Not a big deal on Sandens but something to watch on Yorks and Lehighs.

Either the Sanden SD 5 or 7 series will work and are sold by most aftermarket places. It really depends on the size of your unit. As to the mount, if you already have the York bracket, an inexpensive way to mount the Sanden would be to get a universal York to Sanden mount and use your existing. That way everything should line up with minimal change.
