Hi I'm new to this forum and looking for help with my 72 Duster 340 project. I'm at the resto stage of exhaust for my car.So far I have tried to install 3 different sets of headers on my car with no success.It is a 4-speed, power steering car and both sets of Hookers are tight to the power steering unit and the same on the passenger side on the torsion bar.They also rub at the steering knuckle.and at the idler arm.I know these cars have close tolerances but they are touching now so what happens when I fire this thing up?I'm told TTI's would fit better but Hooker guys said the same thing.If I go with the TTI's they say you have to modify or change the clutch Z-bar.I have even thought of changing the power steering unit to a Borgeson/Bergman aftermarket unit to gain clearances and improve steering. Which way to go?I don't think I can handle another removal.Going broke if I can't get this settled soon! I have even wondered if I should just go back to the stock's that were in it.. Thanks for any input in advance.
