Small block oil filter with headers

The old PH3600's (Fram) are the same thread and gasket as the PH43 (wide short) or PH8A's (wide long) going from memory. I spent 5 and a half years working in a 10 minute oil change shop in the late 80's and early 90's.

The PH3600 was the long skinny filter that went on the ford V6's. Most Ford and Mopar filters all had matching gaskets and threads.
