Looking close (enlarged the picture) at that pic of the oil screen it DOES look more like a piece of gasket. There are 3/401 blocks. '59-'60, '61 & '62-'66. ALL the oil pumps are different. New screens are NOT available. You will have to clean yours as best as possible. The screen usually sits between 1/4"-3/8ths. from the bottom of the pan. I'm sure I can get you a rebuild kit for yours & it will come with new gaskets. I can walk you through the process, but would be better over a land line. No sense buying a used one, you ALREADY have one. The crank is clean because the counterweights are moving through more oil & being cleaned while doing so.
