Bang on mate his is the 5 micron type recon we are on the right track here especialy given the age of the motorThey all fit, BUT!! 63805-80A is a 30 Micron filter for Shovels and evo engines, I think you have a 5 micron one, this is more than probably too fine for the oil pump in your engine.
Evo oil pumps work well enough within the design of the engine. Later filters can cause real problems.
I could be wrong, I often am, but I would NOT use that filter on an evo.
Don't trust HD on this one.
