Hi All, I had to remove the gauge cluster to replace some bulbs, I did remove the front dash pad screws to lift the dash pad. I did not realize there were 2 types of 7 mill hex head screws. I have about 20 that I would say are the standard 7 mill hex heads and 7 that look the same except they are self tappers that have a slightly larger washers. Any idea where the self tappers go ?
