Thanks for the info.. Got all 4 at my local hardware store for $6.09 out the door. Probably didn't need them as in my experience, bolts don't just snap unless they are loose as that is when they become stressed, but for 6 bucks I figured, what the hell. Cheap insurance.You might have problems finding them at a hardware store as they are fine thread and most places like ACE, Lowes and Home Depot only carry course. I did find the lower bolts at Lowes, they had them in a 1.25mm pitch but nobody had fine thread 10mm bolts so I just ordered some from Bolt Depot and got a couple of extras to take with me on trips.
Top bolts are 10mm x 1.25mm x 30mm
Bottom bolts are 8mm x 1.25mm x 25mm
You want a hardness of 12.9
Check your manual for proper torque. I believe the top bolts are 33 ft/lbs and the bottoms are 18 ft/lbs. Use a medium thread locker. I like Vibra-Tite gel. It breaks free at 25 in/lbs vs Loctite which breaks free at around 10 in/lbs.
