Many Ford models only offered under-dash evaporator units thru most of the sixties. These can be used successfully with r134 and give the interior a more vintage look. Basically, you get (or make) the brackets to fit the Sanden compressor to your engine, and you can buy the condensor, dryer, hoses, and end fittings all seperately from vintage air. They even offer a cool bulkhead fitting, so you don't hafta run hoses thru the firewall. The only parts that they don't offer is the two flared hose ends that screw onto the old evaporators, but a well-equipped REAL parts store will have these, and usually their machine shop can crimp the hose ends after you fit and index them...good luck!
P.S. order carefully from Vintage Air because their return policies SUCK!
