Not sure what you're referring to Andrew, could you elaborate? There is a slot that the front screw must go into. Other than fore and aft movement along the length of the slot there are no other location options for the front boss that I am seeing. Unlike the rear boss that appears in a notched area in the body panel, the front edge is located vertically by the screw in the slot. I looked closely at the front boss that screw goes into and there is nothing apparent to me. I have tried leaving the front screw loose enough to allow moving it fore and aft in hopes of finding a sweet spot as I attempt to get the lock cylinder hole aligned, and even tried replacing the original handle carrier that I've modded to take up the slack in the cable that has come with time/use. The best alignment I can get is seeing about 1/2 to 2/3 of the threaded lock cylinder hole I'm aiming for visible through the hole in the carrier, but not close enough for the bolt to find it.
