S/S springs or CalTracks w/mono leaf???

I would also avoid caltacs for the street. had their full suspension on my '65 coronet. mono leafs, bars and adjustable rancho's out back, and 90/10 calverts up front ... That car was stiff ! the front was bouncy obviously but the back was rock solid. I have s/s 002-003 on my 70 dart now and it rides great. just make sure you use the correct long rear shock. I am using the matching extended shocks from Mopar, my wife is yet to complain about the ride and we will go on several hour trips !
