Hotchkis tvs.

Don't fall into the marketing hype of the coilover conversions, they do look trick, provide a little more header clearance, and might weigh slightly less, but the FASTEST road race, handling mopars from our era are torsion bar/leaf equipped. And that TVS is quite a bit cheaper than a full aftermarket replacement. Check out the hotchkiss challenger, and even there 4 door B body to get a idea what's possible
I saw them on jay lenos garage john hotchkis did the suspension on jays 66 Ford galaxy. Looked almost stock but he said it handled like a new car. I had a 67 galaxy I know first hand how bad that thing handled it was horrible. My dart would run circles around it just because it turned so much better. So I was thinking If it would make a boat like a galaxy that much better my dart would drive like a pro touring Haha.
