Oops, Thanks Chopper, 63796-77A is 30 micron filter in CHROME and I feel silly that I did not remember my HD 2004 Sportster Service manual does NOT list the part number, and was one of those things I thought was really dumb when I got it. Naturally I wrote it down on my copy...and spare oil filters are on the shelf in the garage do not even think about it! :small3d007:
