1965 dart, but I am using a coilover setup, no torsion bars. I checked the fit on the engine stand, and no problems once I ground off one middle motor mount. Maybe they moved a tube for the adapter? This Dart has no heater, radio, etc, light weight buckets, Wilwood brakes, and rack and pinion/coilover conversion. 904 trans, 8.8 rear with Ford disc brakes. Any guesses on curb weight?
