TTI Muffler Hanger Issues

Got my TTI Exhaust, and ran into an issue with the muffler hangers provided .

I did their seatbelt trick with their liberty bolts as I only had a single exhaust previously on my 72 Dart. The angle of the brackets is not correct : they angle up towards the floor, not straight down where they should be.

Did I get incorrect brackets? I have a two door which I'm wondering if the seatbelt trick is off no use. If you've installed this, let me know what you did, thank you!
