This happened to me less then 2 weeks ago with 2 of the bolts, luckily the bolts themselves didn't break flush and I was able to use a small screw to slowly turn the bolts out. As said above DO NOT ride your wheeler like that, at the very least the pressure plate will not have even pressure all the way around that is required to function properly, and at worst as quadrider said if and when that bolt vibrates out you'll be spendin a lot more time and money to fix the new problems that lose bolt in your clutch/gears will cause. I didn't feel like waiting to order more oem bolts so I went to home depot and got similiar bolts and washers to replace the broken ones. Everything is still workin great.
