I'm replacing the broken exhaust and managed to break just two bolts. One in the head, The other a turbo bolt. I'll get the bolt out using advice from the forum. My next question is are the bolts special for this application or will regular grade 5 or 8 be acceptable? I don't have a service manual, Is the a torque spec for these bolts?

Thanks,

Aaron

Yes, they are special bolt. If memory serves me right, torque is 37 Ft lbs. MACK
