67 Barracuda Wheel Adjustment

i would do this, and i did this on my car recently when i installed hotchkis strut rods, get under the car with a plumb bob/string. drop marks on the ground from the rear of each torsion bar socket. run a long straight edge across those marks and make a line.
from that line, measure to the marks on the ground that you make from dropping the plumb from the both front lower ball joint bolts in your spindle. your measurements should be roughly the same.

you also want to look real closely at your k-member where your strut rod bushings are, look for any deformation. mine was pulled in on the right side.
the strut rods locate your lower ball joint, which locates your wheels...
