Pulling Engine/Trans over the winter....Header Question??

For some reason I didn't see you wrote TA (Tubular Automotive) instead of TTI - I apologize for that!
I still have a hard time believing they would fit a Demon and not a Dart???
I hope you're happy with the TTI - I have no complaints as of yet.
I am happy with them.
I would prefer the Headman Hustlers.
