I actually just took all of mine out to take to the hardware store and replace with alen heads, and matched em all up. Heres the sizes, Clutch cover 5 EA. M6X20, Mag cover 4 EA. M4X20, Clutch cover 2 EA. M6X30, and 1 EA. M6X40. I hope this was helpful, as it took me hours to find them all, lol. Be careful though, as these lil things can add up in price. It cost me $9.80 for all the covers. I would also recomend hittin with some rustolium primer, and a lil black paint before you use, other wise they will rust fast, and look crappy.
