Like I said, throw that bump steer kit in the trash can and put an original drag link, inner and outer tie rod and adjustment rod, idler arm and pitman arm and you will be perfect. Qa1 made those upper and lower arms to work with factory parts. I'm not aware of these cars every having issues with bump steer unless you use aftermarket parts and change the geometry. In fact when I bought my 70 Duster it had worn out suspension and steering and it still tracked straight and never had bump steer.
