I wasn't sure with directions. 1/2" threads, 3/4" bolts: the spec sheet did not say which determines the tightness. Next to 3/4", grade 8, it says 245 ft lbs, thats impact wrench territory and my wrench is only rated to 150 ft lbs.
I planned on re-torquing the bolts, including the bumper bolts, so I'll go 115 ft lbs.
Thanks.
