TTi dual exhaust '67 dodge dart

Hi, I've just started installing my tti 2.5" dual exhaust. I don't even have my 360 yet, but I'm redoing the fuel lines and you start the exhaust install from the back, so...

Anyway, my question is how close to the gas tank is OK for the passenger side? The driver side looks like there is plenty of space, but on the passenger side the exhaust, just guessing, will be pretty close to the gas tank. I think it's fine, like an inch or so spacing, anyone have pics and/or comments on this? I have heard of people moving their leaf springs outward for 3" exhaust. I have clearance between the leaf and the tank, but it's way closer on that side than the driver side. Pics below
