So here is the deal, kind of stupid but I am getting my bumpers powder coated as we speak. They came off really easy and I expect to put the back one back on in no time.. But my problem is as I took my front off I unbolted everything and slid it off and "clunk two metal parts fall out..? I'm hung up on finding where they go. If anyone could help me that would be great. Write up, picture. Whatever helps is much appreciated thanks!
