[Healeys] spin-on oil filter question

[richard mayor]

About 8 years ago I bought a 6 cylinder spin-on oil filter adapter that
mounted onto the original oil filter housing - at the point where the old
canister style filter was originally fitted.  It uses a KN oil filter part #
HP 2009. I don't recall from who or where I bought it or for how much. I think
I bought it because the other style adaptor had the oil filter coming within a
few millimeters from the starter motor electrical connections.  I didn't think
that was very prudent idea.  I now have a smaller gear reduction starter that
gives me more clearance and I want to sell this adapter and go with a straight
off the block adapter.  Can anyone out there give me any info about the
adapter I have that attaches to the original housing?

 This is for a street Healey car - not my race car.

Thanks, Richard Mayor
