I used sims body bolts and clip nuts for the “corners” that mount to the fender extensions. Used stainless 8-32 bolts and nuts for the small mounting holes along the bottom of the valance. I couldn’t find clip nuts that worked and the nuts are easy to get to. Recommend installing masticated rubber core support seals too. Original installation clips are not available. While smaller in size, sofseal 5075 clips work.
