Fit Issues:
In some situations different stock/brace endcaps may allow the lower to rock back and forth a little or "wiggle". An easy fix for this is to add some thickness to the metal tab where shown in the product pictures. A small rectangular piece of electrical tape cut to fit this space usually works perfectly.
