yeah don’t do that. If the alignment is out of whack there’s a reason. Gotta find the reason first before cobbling it up. Spacers like that shouldn’t be necessary if everything is right.
You should be able to tell which way the offset bushings are installed by unbolting the UCA. You can leave the ball joint attached to the spindle, just be sure to loosen the torsion bar adjusting bolts so there’s no tension on the UCA before you unbolt it.
