New Mancini Timing Cover Fitment Issue

I haven't seen anything yet, but it's very obviously different. Will it work? I reckon only you can answer that when you mock it up.
I'm going to clean up my original and glob up the water jackets with RTV adding to what was there when I popped the cover off.

I'll go the grinding route on the oddball aftermarket to see if I could make it work.
