Thanks for the info. I thought all the early air cleaners were oil bath. I guess I was wrong. I had a 50 PU but don't remember what the air cleaner looked like (old age) That was a few years ago. Guess I need to dig out my pictures. The filter I have has no number on it. I have to push hard to get the threads through the lid. It is a little wide. It needs shaved a little around the rubber edge so it will fit inside the lid better. Thanks everyone for your help.
