Hey, I'm restoring a 1975 Dino GT4. I bought the Classic Air A/C upgrade kit based on one of the threads here. The trouble is that the replacement evap blower, the one that blows air into the interior, is a much different style than the one on my car. The stock one looks like a snail and is just like the two blowers in the front corners of the car. The replacement is more like a tube with cages spinning inside tube. Worst case is I have to just reuse original fan. But if there's a better option, I'd sure appreciate any tips. Thanks!
The two snail like ones located at the front of each front wheel arch are for the non a/c cabin ventilation pushing air through the two outer dashboard vents. The one you have sounds correct for the a/c blower which is located in the centre of the front trunk bulkhead and pushes air through the centre dash vent, the two vents by your knee and the footwell vents
The OP has this type of (snail) evaporator blower that was used up to SN 12162: https://www.ferrariparts.co.uk/diagram/ferrari/308-gt4-dino-1976/040-air-conditioning-system-(up-to-n-12162) The Maranello Concessionaires (substitute) price isn't crazy if your AC kit vendor can't supply.
Thanks you Steve. Yeah, that's it. Mine is SN 09082. Ahh drat. I hoped there was some sort of an adaptor for the more modern, presumably more powerful fan.
