I have one pair of flappers that look like the reproductions being sold. The others have a coil spring thermostat that activates the movement of the flap. PET shows one part number from 1965 on but I suspect the ones with springs were SWB and Porsche changed the design to the later one. The coil spring ones had heavy rust and one housing is very thin in the area around the vent holes. They were disassembled and soaked in Evapo-Rust. Not all parts are shown in the picture. The other pair are dirty but in very good condition. I do not need them and if some one needs these for an original restoration I will be glad to part with them.
Any information is welcome.
