anyone have fitment issues ASCO RSB07 in distributor?

I am replacing my old suspected defective CAS with a new one from ASCO. When installing the new CAS I saw there is an issue with clearance of the trigger disc and a CAS mounting screw. Specifically the front driver side screw. After I f…ing cracked the housing tightening it down, I removed it and compared to the original RSB03. One difference I noticed was a leg or standoff on the bottom side in that area which is not on the old RSB03. I filed it down then reinstalled and it now fits. Wanted to see if others had a similar issue. I JB welded it and pray its just the casing and not the electronics. I'll try to run it tomorrow as tonight I need to medicate with a few beers.
