Thanks but anywhere in the united states lol

Would this work to put a 16mm noctigon into a 20-21mm pill opening to help a little with centering and heat path.

I looked too and couldn’t find any stateside. At least that AliExpress link is cheaper

These might work. Just have to dremel the inside a little

I use something like that for my Subaru oil drain plug but I dont remember them being that expensive. Got em at dealer IIRC around a buck a piece.

Guess I am the one getting ripped off. I just noticed that was a 20 pack.
