Michael: I believe the part no. Bruce is refering to is VAA-50615-VUH. Parr Automotive sells them for $199. I used a unit from Southern Air sold by Southern Rods and Parts, a 7" cube that would fit under the Unique dash.($110) I had to fabricate ducting for the defrost vents and it does not have a true 3-speed motor. I used a 3-speed switch.
Parr 405-942-8677
Southern 800-787-8763
These guys and many others advertise in Street Rodder, etc.
Good Luck, Kirby
