Pretty sure these are the sizes: Starter bolts: 2-m8x1.25 40mm w/ a 13 mm head (top two) - grade 8 1-m12x1.75 40mm - grade 8 - can't recall the head size. Use loctite on the larger bolt to keep it on (low strength). The theory is that the aluminum threads set the torque spec and that the spec is insufficient torque (don't want to strip the aluminum threads) to "stretch" an M12 bolt (tty bolt).
I want to confirm i just used these and its 100% on. using these measurements with gr8 bolts also i used the 60mm long bolt and put a nut on the protrusion as insurance also worked perfect.
