The brass fittings on my spare 904 where the cooler lines attach are both cross-threaded. I'm hoping someone can tell me what threads these things use. I've had bad luck at the local hardware store finding anything that matches up, so I'll probably have to order something online.

It looks like 1/8" NPT threads on the side that screws into the transmission, and something like AN threads where the lines attach. The one in the picture below is a 45 degree fitting that goes in the rear position, but the front fitting is straight.

It looks like a brake line flair fitting.
