Installing Accurate dual exhaust on ‘67 Barracuda

I have 2.5 inch TTI's on my 67 Barracuda. I didn't remember having to do anything to the strap, but looking just now I see I bent the strap to clear the right side pipe.

My mufflers do not sit level. They are almost an inch and a half higher in the back than in the front.

I tried to take pix, but it's very difficult to do with the car sitting on the ground.
