It can't be hard to replace. I have a bucket for spare metric bolts that usually provides what I need, but NAPA & Lowe's sell them if my bucket doesn't have it.
You are correct in that they are fine if you use don't torque them down too tight and break them but they are hollow for venting gearcase pressure and a solid bolt will cause that pressure to pass through the bearings and seals.
