Keep looking over in CEG for one in the classifieds. I've seen several lately that people are selling. If you want one right away you can try to reach Bill Jenkins on CEG and he can see what they run from the dealership with discount.
If you go to a local body shop or something they should be able to order just the inserts. Because i had to order a new side skirt and not knowing that it came with the inserts i ordered two inserts on top of that. But i had them sent back. Let me check i may have a set of them in my garege. i will get back to you
They can be purchased separately. I don't have the part #, but contact Bill Jenkins, or Steve @ Tousley Ford, and let them know that you need just the "jack point covers," and not the entire side skirt. I want to say they are either $20 or $30 each.
