bolt size?- XS Power fmic install

[mygsx2120]

I am in the process of installing my xs power/ssac fmic and I can't mount it because I am unable to find the right bolt sizes for the existing fog light holes. The tech write-up says they are 10mm, but when I bought some they were too big. I went back and picked up a couple different sizes, but still none work. It looks like a 7mm is the right size but it still will not thread. I know there are plenty of people on here who are running this kit, could some one please let me know exactly what size it is that I need.

If by chance the holes are stripped, any advice on how to mount it? This is my driver, so I need it back on the road ASAP. Any help is greatly appreciated, thank you in advance.

all of the bolts for the front of the car that hold things together that are 10mm heads have the same exact thread. Get one of the bolts out of your box-o-bolts from taking the car apart, go to home depot, and go match the threads with the fog light bolt you brought. Thats exactly what I did and I had no problems finding the bolt at Home Depot.
