I need to know the size of the motor mount bolts, not the head size, but the actual pitch diameter of the bolt/stud...I was thinking Its a 10mm or 12mm, but I'm not sure...tomorrow I am gonna make some solid aluminum mounts at school and I need to know how big to bore out my holes, so If anyone has a mount laying around pleeeaaase let me know the size
thanks!
