Thanks in advance for any help - I noticed that one of my underbody panels is hanging down and on closer inspection I appear to have lost two bolts that hold the panel up to the metal lattice grid front-center of the car. Does anyone have an idea of the part number for these bolts?

 

I think you are after a couple of the "underbody shield screws" part number C2C22719, see here:

Another strategy would be to remove one of the other screws holding that panel. Then, bring it to a hardware store and match up the thread size and length.

Extra points if you buy shiny stainless steel. Other owners will be envious!

 

Thanks! That's a helpful link / ref number. I considered using one of the front fasteners but I wasn't convinced they are the same - wouldn't hurt to try though. Appreciate the idea.
