Stop in for a cup of coffee

I have a quick question that i wanna post here since it doesn't deserve an entire thread... i put a new Spectra tank in my 62 with a new sending unit and the lock ring seems to actually be too small in diameter and i had to play around to get it to seat on all the tabs.. i have read that they all pretty much leak.
I saw a guy here or on FBO selling "Factory" rings, is that really a thing? are the aftermarket ones that bad?
Really a thing. The new rings are thinner and seem to always leak. am that guy by the way.
