Hello. My name is Victor and I am from Barcelona. I own a 95 Mazda RX7 that has an aluminium Koyo Racing radiator, impossible to find here, in Spain. That's the problem of owning one of the only 6 FD lasting in Spain :-( I’ve had a little problem with it. I’ve broken the lower radiator cap (the plastic one for emptying the radiator) and it’s impossible for me to find another one, or another cap that could be useful with the same kind of thread, because this thread doesn’t exist here! So could it be possible for you to find a cap that can be used in the koyo radiator? I’ll pay for all shipping you tell me. Thanks!!!!

Victor

 

You could retap the threads to match something you can find locally.

I never understood why they used plastic for those...
