just to clarify

[Mr.PFloyd]

Shank Diameter (mm)....Bolt Head Size (mm)....Thread Pitch....Example
12..............................17................ ............1.25...............Flywheel Bolts

since their shank diameter is 12 mm, is it an m10 i need? i suck at buying bolts... lol.

you need a m12x1.25 x whatever the length of the threads are.....probably 20 or 25 or so....
