I think that is all the factory did. I do not think I have any 360 or the Mopar Performance windage trays left to check. I'd slot both sides out to keep it centered. Have you tried your windage try to see if it fits yet?
I test fit the windage tray, and the holes dont line up, but only slightly. I will just elongate the holes a bit on both sides in order to make it fit. I dont expect to have any problems, I will just spin the motor over a few times to make sure I dont have any clearance issues.
