Torsion Bar Upgrade for '65 Barracuda Formula S

i ran the MP oval track springs in my 1st 65 dart. they were well matched to the 990 t-bars rate wise. the front sway bar was a 1.250" and i had a 9/16" rear bar. the combo was really well balanced and sure footed with out being too heavy or overbearing on the street. better shocks would've made it more livable though.
