Peeing on the quarter....

.....anybody have a fix for it? Short of not filling up all the way.....or shortening the filler tube so you fill it from the trunk....Had a company bookmarked that had a fix for the peeing problem but it was for 66 and earlier A-bodies if I remember correctly. But that was several laptops ago. Had a subscription to a thread discussing this but can't find that either.
Would like to keep the factory tank. Dart has relocated springs but found a local guy with a Mandrel bender that thinks he will be able to squeeze a 3" tailpipe next to the tank.
