Right now the rod bolt I have the head is 3/8 but the diameter of the bolt is 5/16 . I somebody have the newest rod can tell me what size is the head of the bolt ? Thanks again...........Omar
did you buy them new? does the head of the bolt say ARP 2000 ? i would assume they are refering to the thread size and not the bolt head.
