My oil cooler lines are leaking from the crimps for a third time, and I was thinking about making some braided -10 AN lines from Summit. I know the adaptor block is 3/8 npt, but I don't know about the ports on the radiator, and I plan to take the lines to the local hydraulic shop to tell me what size, pitch etc. they are. I recall seeing photos of this done on an external cooler for a 6.5, but I don't remember where or by whom. Thoughts or discussion on this is appreciated.
