I've heard that in general all automotive bolts (except maybe bumber bolts) are grade 5, and that GRADE 8 bolts are refered to as tractor bolts. Grade 8 bolts are harder and have more shear resistance, but are more brittle and can fail under a sharp blow. Any ideas where grade 8 bolts would be needed on a power wagon? Imparticularly I'm wondering about the bolts that hold the front motor mount bracket to the cross member. Thanks.
