Anybody know the thread type and size for the i engine oil cooler adapter fittings? I am fitting a larger oil cooler (RX7) to the car. I intend to use AN fittings and SS braided hose. I imagine that I need metric to AN adapters in the oil cooler adapter, though I have seen BSP theads used on other Euro engines.

I measured the diam. and thread pitch. It looks like a 20X1.5mm.

I took mine to a local hydraulic fittings shop and he said it was some thread that's normally used on German tractors. :-k Luckily he had just the thing to adapt it to 1/2in pipe thread. =D>
