Oil cooler adapted to a 1982 CB650

I found a guy in Oz who machines an adapter plate in between the oil filter cover and the crankcase. We will run lines going in and out of the adapter plate up to an oil cooler from a later model bike like a CB900 or a nighthawk from the mid-80's.

He needed a picture of the area just to machine it perfectly so I posted some here for him.

I'll have to remove the horn I bet, hopefully I can keep my chains that work as my bar stop so that the clubmans don't hit the tank.
