Unless your car has been in an accident and has a bent axle the only adjustment that can be made besides making sure the front wheel bearings are set right is the toe-in. My 28 had a wheel wobble problem when it would hit a rough spot, and the front tires were wearing where they appeared to be scuffing. I checked the wheel bearings then the toe-in and it had toe-out of 1/4" I adjusted the tierod between the left and right wheels to 1/8" toe in and it now steers and rides great. Some where in the old threads on this site,is a detailed home shop way to check and adjust toe-in.
I think that in the 27-28 repair manual there are specs for the alignment of the front axle.
