Sump screens for A65 and for Singles have a different location for the hole. Furthermore, on one of the aluminum aftermarket sumps I have, you cannot put the screen in the proper way because the raised rim needs to be down and the sump is not relieved for the rim. I had to mill a recess in the sump to get it to fit. Tom
It all depends on the positioning of the oil tube that the factory did. They are not all in the exact same position. In all cases turning the screen over did not align it. I had to move the hole in the screen using JB Weld.
