If one broke I'd suggest getting all 6 as the others are probably stretched as well.

Its hard to see in my picture but these special bolts have a "shoulder" and are there to ensure the pressure plate is centered. If you take a look at your flywheel holes you will see that the threads do not come all the way to the top for that reason.

People have and continue to use regular bolts which work.... but theirs always a chance you might get a vibration.

5/16NC X 1-1/16, I have heard 1 inch long work. You will need 5/16 lock washers also.

To answer your question I believe they are grade 5. I'm sure someone here can confirm that.

I just want to make it clear that I am not criticizing anyone's choice on hardware. I always say it's your jeep so you need to decide what you think is best.

Hope this helps!

Have a great day :D

We use studs instead of bolts to avoid this issue. Not original but very functional. Same goes for the cylinder head.
