I am getting ready to set the front end alignment on my 68SS and I was wondering which alignment tool do you guys think is the best. I have searched for more information on both types, but there is not really a preference, only instructions. I have SC&C adjustable uppers, tall ball joints and stock lower arms.

Thanks

string, jackstands, a bubble level, an angle finder, a tape measure, and a level concrete floor are all you really need to do a good alignmnet.
it might take you a weekend to figure it out, but once you get the system down, it becomes really easy.
