just a shot at it but i was wondering if theres any dsm guys around ocala or in the thread... im trying to find out if the 4g's come factory with 12mm 12point head bolts or not... ive worked on a few 4gs and they didnt have them they were 12mm 6point... there not stamped arp so i dunno but there identical to my arps... rep will be given for info or where i can find out for sure or if someone can look at them and tell me...
