A little advice here

Thats what I figgered. Why wouldnt they just shorten the plates to make them fit sway and non sway vehicles

Others have asked why they dont offer plates that include sway bar tabs. One answer fits all. Those tabs were in 2 different locations from the factory.
I wouldn't produce several different types and part numbers for right hand and left hand either. If I did someone without sway bar tabs would ask, "What are all the notches for ?" LOL
