Missing hardware to attach bellypan
My car has been without some bottom front trim pieces for a while due to an accident and them never being replaced. Now I'm getting a new bumper cover installed as well as the plastic belly pan (p/n 51718268344). Turns out there's missing hardware that the pan needs to attach to..I THINK it's the left and right mounting brackets p/n 51717894722 and 51717894721. I'm also missing the brake ducts. But HOLY COW why is the right duct alone $350??? That's outrageous. Can I do without those? Does anyone know for sure if they're required for mounting the belly pan? Any help is greatly appreciated.
