65GTinwork

Working on my 65 GT fastback... got to attaching the H-pipe to the Tri-Y headers, ha... alignment is way off. The right header comes in at an angle and throws the right side of the H-pipe way to the left. Anyone run into this problem? Checked another H-pipe at NPD, matches the one I got from Mustangs Unlimited. The rest of the system is new standard GT dual system. Could use any advice from anyone with experience installing Tri-Y headers, H-pipe and stock GT dual exhaust system.
