hey guys i have already mentioned them, but here are pictures. you all say razordaves pix of his secondary bolt stretched out. here is a primary that i took out this weekend. notice how it is stretched. these new bolts i have wont stretch or break, equivelent to a grade 13, nearly twice as hard as a grade 8 bolt! these new bolts use a metric allen. you can buy metric allen impact sockets at most any sears, or most any auto parts store!
