Oil Cooler Fittings

[MrG 3]

Just after some information, I'm nowhere near my car and I am after the std size of the fixings/pipework for the oil cooler pipework.

I can't remember off the top of my head, but I do know they are extremely weird and wonderful sizes, especially the sandwich plate end.

I had some new pipes made for mine, they were able to supply new fittings to go to the cooler, but they had to re-use the unions at the sandwich plate end.
