Alignment Help

Hi,
I have a 68 Dart GTS which has been completely rebuilt. I do not like the way it 'wanders' at highway speed. In reading various forum posts it appears that I need to get more camber/caster. I have purchased Moog K7030 caster/camber adjusting kit. I am wondering if that will give me enough caster as some members indicate these cars need with modern tires. I am hoping to get 4 or even 5 degrees positive caster and would appreciate any help in knowing if the parts I have purchased will give me enough adjustment to get that or if I have to also get offset bushings Moog K-7103. All of the steering components on the car are new. Caster is currently .2 on left side and .9 on the right side. Wheels are new and tires are Radial TA's.
1 of ur problems is that there is too much difference in caster between the 2 sides. Shouldn’t have more than .2 more in the passenger side. Kim
