Yeah exactly. This is the driver's side from my Duster when I misguidedly decided I wanted to run TTI shorties instead to get better ground clearance (yeah not how that worked). The two red arrows show the only contact points, I dimpled these a little more before reinstalling. But again, that was for the 1.12" bars. No other modifications needed, the passenger side got a matching set for the torsion bar on that side. I have noticed, just in general from reading install threads here, that the biscuit-style engine mount cars seem to do a little better with TTI's, while the spool-style engine mount cars seem to do better with Doug's. But that's just a really basic trend I've noticed. Mine is a '74 so it has the spool style mounts.
