I have a 1964 dodge dart gt convertible, and when i make a turn... boy does it roll! Torsion bars are ok , it's a 225 slant with a k member in place. I've read and looked that one solution is anti sway bars but don't really know which ones to get??? Is there some for the front and some for the back? Do i need to get them both? Is that what i need? I would'nt want to roll out of the car on my next turn with the top down. Any suggestions?
