Clay,
That is the one that is in my unique. (the Flex-a-lite) (not the greatest looking unit, but it came with the car and works well (when the permanent magnets are not coming unglued from the motor case thus requiring disassembly and re- bonding in the middle of the friggen Austin Cobra meet
), so I have not replaced it ----Yet]
) My car never had the sway bar so it fits. Have you driven your car without a sway bar? Just curious as to how much difference it makes.
My friends car has an existing 16" fan that looks almost identical to the new Spal unit we ordered. I had spent allot of time making him a custom fan shroud and don't want to have to redo it, so the Spal fits our criteria well.
My Unique:
My friend Paul Risch's Classic Roadsters Cobra that we had to totally rebuild. (long, tragic story) The Spal should just about be a bolt-on to the hand made shroud, so it was a logical choice for us.
