Help with Addco Sway Bar

No fabrication is required.
When a owner has a pre 73 A-body with pre 73 brakes and a a sway bar ( either OEM or aftermarket ) they are fine and dandy. That is until they try to install 73 up spindles and rotors exactly as they were pulled from the donor.
When they notice the late model calipers position is going to hit their sway bar they see a simple and possible solution. Moments later they realize that moving the caliper and its bracket will require switching the spindles.
They now have 1 critical question to find an answer to... Are these spindles left and right specific in regards to suspension and alignment ? The answer is No. The ball joint bores are plumb. The tie rod attach point isn't cast as part of the spindle either so the spindle itself will work on either side. Happy moparing.
We owe Ma Mopar much thanks for the part in bold even if the story doesn't go as told here for everyone.
