More gas tank revisitied

[Goose]

So far the two options on '67-'72 gas tanks is to live with it or move it. I choose to live with it and have for 39 years. But, I would like to hear a discussion from some folks using the stock installation who have figured out how not to spill gas in right hand turns, ruin paint jobs, and create the gas fume issue. Of course the quick answer is don't fill the tank up, but has anyone tried installing any baffling, better seals, designed or found a better cap, ....or something? Thanks.
