Classic Auto Air Installation 74 Dart Sport
Thought I would finish off this thread and my installation. After getting all the adjustments right I reinstalled the dash control and underdash box. Everything worked correctly. Oh, as suggested by someone I cut the back off the original plastic glove box, shortened the depth, then glued the back back on, worked great! Put their remake glove box in the trash.
Next installed the condenser, compressor, fridge and heater lines/hoses. Since I have a 26 inch radiator and core support the flat plate brackets for mounting the condenser were too short, I used two of theirs and made 2 new ones.
I didn't like how the compressor mounted using their supplied engine brackets. IMO it made the compressor set too far forward and too low. It also did not fit my alternator mounting so I ended up not using their crank pulley or mounting brackets. Their support brackets for the main compressor bracket and idler did not match anything on my 360 engine with Edelbrock intake.
I already had a double crank pulley and brackets for the old style R4 compressor from another 360 engine and with a little modification I think it works better. Its also easy to get to the intake heater hose fitting behind the compressor. The only real issue is the low pressure line connection to the compressor, the port is facing the wrong direction, it faces the air breather, it should face away toward the front of the engine/car. Their instructions & picture shows it that way but the actual hose they give you is wrong.
My reorienting of the compressor mount meant that the high pressure line was too short to fit the factory hole in the right side core support, I had to drill a new hole about 3 inches to the right, and lost the use of the stock radiator overflow container. I have a new 3 inch x 10 inch chrome tube overflow coming from Classic Industries that should work perfect.
After all the connections were made, I pulled a vacuum on the system for about an hour, let it set and showed no signs of vacuum leakage. Charged the system and it works perfect.
All in all it worked out OK with some modifications (dash control) to fit the 73 and up cars. You can get their new fan switch mounted in the dash control assy so it operates the system and looks normal on the face plate. I don't know why they wont include in their instructions how to install this system in 73 and up cars, its not that different or difficult, though as I suspect they don't want to deal with the plastic dash control assemblies. I was pleasantly surprised the fan motor noise inside the car isn't that bad at all when its on high.
