Depends on how far away from the center (shaft) the bolts are located. The farther way the more leverage (and less Load) the bolts have on the motor. You could calculate load by multiplying foot lbs exerted by the motor and the % of a foot the bolts are away(SOMEONE CHECK MY MATH I THINK I NEED THE INVERSE) from the center then make an educated decision.
Off the top of my head I say/ guess Motor mount bolts Grade 8 rest of stuff Grade 4.
