The difference is the tread size that goes into the engine block. One is 3/8 and the other in 1/2. I think mine was 3/8??? They can be found at a good hardware store or parts house. Just need the 45 degree bend. I know the non oil pressure gauge dash (or idiot lights) uses a different fitting to the one that has an oil pressure gauge.
