Front End setup help

If your using poly strut bushings with 67-72 struts it will push the lower control arm off of the stud as you tightening the front nut on the strut when the torsion bar is not in place and will bind the suspension once everything is put together, the poly bushings are too thick for the 67-72 a body struts, they are designed for B and E bodies.
You have three choices at this point:
1: use rubber strut bushings for 67-72 struts
2: buy adjustable struts or 73-76 struts
3: cut 3/8" off the rear strut bushing and use the cut off piece on the front side of the strut to take up the difference.
