In my 68 122 I am using a Sanden 507 . You can also use a Sanden 508 . It requires a different bracket. Bob Foltz has them and the belt tension pulley. Call him at 570 689- 2886. He is in Pa. The condenser I chose is the smallest that would fit. I also installed a BeeCool radiator from Summit Racing. It is universal fit for GM. I used Chevy hoses with copper pipe reducers to connect to Volvo hoses. I stuffed a 16 inch Zirgo electric fan between the condenser and radiator. NYC heat can be unforgiving in traffic so I need to move as much air as possible. The evap used to be the original Volvo Frgiking. I sold it to Joe Lazenby and got an original 4 outlet unit from a 1965 Mustang. To make this one fit I had to install a short shifter from an 1800. I feel it should have been this way from day one. But that's me. So far I can sit in traffic on the worst of days and idle temp with the air on is around 180 degrees using an Autometer temp gauge.
