Thanks for the pictures "go wild", I'm going to be doing that this weekend hopefully. I also found matching threaded rod and a couple barrel nuts to extend the 20lb tank mounting brackets to fit the 30lb tank. This way I don't have to struggle with that nut & bolt in the bottom ring. Got everything I need for $5 at Home Depot to modify the tank brackets.
