"Total" rebuild??

I have a 74' Duster that behaved the way you describe before putting in an Addco 1-1/8" front bar. It seems like a different car now. Nice and tight in the turns, no body roll. I have a 7/8" bar ready to install in the rear soon as I get time. I expect the handling to be very neutral after that - flat cornering with all four tires breaking loose predictably at about the same time...
