I am working on my air cleaner assembly and would like to hear from someone with more knowledge than myself on the benefits of keeping the copper strainer, or looking for a later type of paper element. I would keep the copper element and clean it according to the shop manual and set it aside, but as a daily driver maybe the paper element would be better??? After much searching and some good advice from the guys I found that the Fram CA6605 will work for my Oil Bath Air Filter on the 1940 Super C
