The stainless steel bolts around the top of the flares are for looks and do bolt to the body... Bushwacker fender flares use the screw holes at the three o'clock and ten o'clock position in the stock fender plus they come with clips to connect the flares at the twelve o'clock position on the stock fender. There is a rubber seal that I had to run along the top of the flare which avoids paint damage... The stainless steel bolts required me to drill holes in the marked position for bolt placement... It took me about four hours to install, but I took my time and I wanted to be sure it was done correctly... I am very pleased with the results... I would do it again in a flash...
If you you look closely you will see the connecting screw on the inside of the fender flare...
