I had to google OEM, Lol!
Some of the bolts are visible on the surface where the fenders and running boards bolt together. Not many. I will end up using OEM bolts for those visible areas and new ones for most of the bolts that are underneath and not visible. I think I have enough to do that. Many of the bolts snapped off or had to be grinded off even after much soaking in penetrating oil and heated with a torch.
But I think I have enough for the visible areas.
Thanks for the tips guys!
