Fitting an oil filter mounting

Hello,

Was wondering if there is a "correct" position for fitting the oil filter housing on the engine frame, is there a template ?.

This link should answer your questions:

Thanks.

Speaking of fitting an oil filter mounting, I have noticed a couple of Nortons where a oil filter was mounted onto a nice triangular shaped casting that bolts to the inside of the timing cover, where the points housing would have been on the early (1968) Commandos. The filer mount bolts up using the original bolt holes for the blanking plate. It sits nicely in the space behind the barrels, and looks right.

Does anybody know if this triangular shaped filter body is still available?

Thanks,

Stephen Hill
