How expensive are the Doug's? might have to try a set. Anybody got the TTI's on a spool mount car? {'73 up} wondering if I may have the same issues? Have not made a choice on headers. {might end up fabbing my own}
I have the TTI 1 5/8"-1 3/4" step headers on my '75 Dart Sport race car. OEM replacement poly spool mounts and OEM manual steering/suspension. I think them touching a torsion bar was the only issue I ever had. But that can be cured by a little wiggling of the engine while lowering. I usually tighten everything (including engine side mount bolts) after it's in place. Relatively east to install, especially the passenger side. And you don't need a 90* adapter.
