TTI Problems - Annoyed!

I installed them on my 66 Dart 408 stroker. Didnt fit worth a damn. Checked the k frame measurements and was where it was supposed to be. Called TTI only to hear the service tach say we have many out there that fit, the mandrels dont change so it must be my issue. I heated and dented and bent as needed. Still not running yet so I dont know how they will work once motor twists and moves. I do have a strap on drivers side.
I dont think I had any other options so I gotta live with it.
