'67 A-Body dual exhaust t/pipe question

OK...calling all you '67 A body owners who have installed dual exhaust. How'd you get the passenger side tailpipe around the gas tank strap bolt. I think this only applies to '67 w/ the east/west tank strap, as later tanks had the 2 north/south tank straps...and the gas tank is shifted to the passenger side as well.

Are all A body gas tanks biased to the passenger side?
