I've re-used the stock screws at the owners request. I use a Q-tip and cleaner to swab out the threads, clean the screw, install a star washer (thin - doesn't take much thread grab away) and blue loctite. No issues to date. I don't know what year they started with the allen head screws and those even have a bigger shoulder to grab the star washer with.
Sunthechip - headlight surround looks great! Part of the fun of a DR....making it yours.
