Hi, I need help again. Has anyone installed a TTI 2.5" exhaust system on a 71 or 3rd gen Charger? I'm about to install mine, and the instruction that came with the system said drill new holes for the main new body brackets. It also said "Mount the bracket 7.5" from the floor(arrow pointing up) and 6.5" from the frame". If anyone did one before, please let me know how it went. I just wanted to make sure the deminsion will work before I start drilling. Thanks.
