side skirt rivets

[M3Bob]

Hi all. I'm putting my side skirts back on after doing a repair on one of them....and it's been 6 months. I'm blanking on where the 51118174184 (gray) rivets go (one per side) vs. the 51118174185 (black) go (10 or 11 per side). Does it really matter...probably not, but i'd like to try to keep the old girl as close to original as i can (barring certain other upgrades!)

Thanks!!

The gray are longer and go on the point where there are a couple of layers of plastic undertray etc, towards the rear.

Thanks...that was my guess (either the front or the back). I've got a couple of the plastic trim pieces over the RTABs to put back next time the car is jacked up, and a few zipties i'd like to replace with the proper cable holders.
