3" exhaust w/ relocated springs ?

i have a few pictures somewhere of how others have snaked 3" tailpipes out the back. i have been in contact with http://jimkellemsmotorsports.com/ReplacementGasTanks.html whoever makes there tanks builds them out of aluminum, they are a copy of the original design with the addition of some baffles. they told me that they should be able to have the tank built a few inches narrower and then made deeper to regain the lost capacity. the GSS Hemi Darts had a "mini tub" fuel tank built by Ricks Hot Rod shop, or something like that, but he no longer makes the tank. not a very good picture but it is all I could find of the GSS Dart from the back....
