Anybody who wants to flip the chunk around I now have a good template you can borrow instead of buying a gasket.
I cut the top off a chunk I had laying around so now it's just the mounting flange. So now you'll have a good 1/2" of metal to guide you or use this for the center punchs/screw in punches.
Free to borrow, just bring it back because it was a pain to cut the top off.
