Lowering a 67 dart

I would look for another option to lower the front. Cranking down the torsion bars completely removes spring resistance to bumps. May look cool but rides like crap. I did it on my 76 Charger and busted a lower ball joint on a pothole. Ripped it out of the a frame. I would search the web and find dropped spindles if anyone makes them so as not to change suspension geometryor try a low profile tire package. The hi tech way would be to air bag it but this is expensive. Nothing worse than a nice car that rides like crap. With the extra rb weight I would not even consider this option. search the suspension threads and good luck with your project.
