I’m installing some side skirts and I wanted to use the stock nylon nuts to secure the ends to the car. I plan on using the 3m Tape in the spots down the middle I’m mainly missing the front nylon nuts and I don’t know that size as my car didn’t have the front mud deflectors on it. I could use a few of the longer rear ones 17mm if anyone has those as well. They sell them in bulk on this site I figured someone had to have them.
