These parts were removed from my '69 Cutlass when I had the Vintage Air system installed.
The AC delete plate is made by AGM and includes a new fan motor, squirrel cage & the ever elusive fan resistor. It lets you ditch the massive under hood stuff (evap, compressor, condenser) and keep the factory heat. Should work on any 68-72 A-body. $100 plus the ride.
Flex fan also has a 2" spacer and fit nicely on my '69 350 with factory AC. $20 plus the ride.
