I recently upgraded my diff covers to Rock Crushers. I'm not 100% happy with the bolts that are supplied - As you tighten them down, the socket makes contact with the cover & it is difficult to ensure I am getting the correct torque applied - I would like to replace them with Hex head bolts. Does anyone know the stock bolt size?

The Rock Crusher came with new bolts - They would be the same size as the stock bolts, just slightly longer.

Thanks
