Maybe one of you can shed some light on this.

The torque specs for the motor mount through bolts(ones that run threw the clamshell and hold the motor to the K member) have some confusing tq specs listed.

Engine Mount Through Bolt Nut - 59 ft. lbs

Engine Mount Through Bolt Screw - 70 ft. lbs

This confuses me bc they just thread into eachother... so i do hold the nut with a wrench and torque the screw to 70ft, and then hold the screw head with a wrench and tighten the nut to 59ft?
