My 66 has always had a setup I cobbled together in 1993.  It performed perfectly until Mastercraft worked on my car, destroying the condenser.  It consisted of an original 66 underdash unit, an aftermarket condenser, an inline dryer, some custom hoses and a York aluminum compressor.  Right before the Florida BASH trip, the york finally crapped out, so I installed a Sanden .  It has been runing happily on R-12 right up until the mastercrap fiasco.  I still have four cans of R-12. so I have to decide whether to go back R-12 or go ahead and convert it, since I will be buying a new condenser anyway.

In town, the underdash unit will freeze you out.  It is less effective on the highway due to leakage around the windows at high speed, but the unit is still making cold air.  Only drawback of this type system is there is no connection between AC and DEFROST mode.  When we were coming through Arkansas, coming home from the Illinois bash, I had the AC going as well as the defroster blowing to keep the windshield clear during some pesky rain in the mountains.

If you consider an aftermarket unit, find out how hard the thing blows and how much noise it makes before purchasing.

IF I ever get AC I will look real hard at the new units that go completely under/inside the dash. I don't like the old style which intails cutting part of my console away. Seen'm at swap meet/car shows and according to the sales man its a bolt-right-in deal.

Rudi, I'm glad to hear from someone that has experience with the CAA setup.  My son and I went to a carshow last weekend in Denton. It was an open house for RSS restoration shop. We weren't there 10 minutes when asked if we were interested in filling out a FREE raffle ticket. I said sure, even though I never when anything. The last drawing was for a $1200 gift certificate to Classic Auto Air and we WON!

are all the systems like that?  I haven't looked at them yet.  I'm scared of the price.
