FYI - TTI Header Clearance Issue (Solution)
I don't see this as a solution for all...but maybe a few..
On our '75 Duster...no mods, bends or whatever were required to install our ceramic TTis... it was all tight ...even threading out torsion bar through them..
When we were installing them, I asked the same question . I found that many on this board were able to install them without mods..
Is you engine aligned properly.
Great pics though..
