So here it is, I purchased a heat sink adapter for a tank that the threads were gone enough that it wouldn't screw into my mod and fixed it. Then the threads in my newer mod just went out and it fixed that as well. It didn't even occur to me that my old mod with a recessed pin that would only work with long pin tanks could be fixed with one as well... fixed 2 mods for $4.
