    Does anyone know the center to center length of the uppers and lowers for a 68-72 GS? I think it’s 22 inches on the lowers, 10 1/4 on the uppers.
    Final question - stock sway bar is two holes 6 inches apart on centres. Is the first sway bar hole 4 1/2 or 4 3/4 from the rear control arm bushing center?

    Thanks

    BUICKRAT Got any treats?

    They look great but I don't see a spacer in the sway bar holes? Without a spacer, when you tighten the sway bar bolts, you will collapse the control arm.

    Yes spacers have been welded in. Using the Johnny joints from moser for the ears of the differential.
