I recently upgraded to the M5 guibo, during installaion I noticed that the M3 bolts where too short due to the fact that the M5 guibo is some what thicker that the origional. I remembered reading that It was recomended to upgrade to the M5 bolts, so I ordered a set. When I received the new bolts I noticed that they were the same size as the origional,with the only difference being the grade, 8.8 for the M3 and 10.9 for the M5. Where can I aquire longer bolts??????
