[Rapid Ride]

Hello, I'm new to this site and a new superformance cobra owner. I am working on repairing the car I bought. I have found that parts very hard to find. I am looking for a fan blade, not one of the little ones in front of the radiator, but one of the functional ones located inside on the shroud. It is mounted to a Bosch motor, but the fan itself only says "Germany" and a few numbers. Anyone have any idea where I can find this part? I looked on the hillbank/ superformance site, but it is not listed there. Any help would be appreciated. Are there other parts sources for these cars? Thanks in advance for your help
