Hey Dave, yes, I can definitely help with that. For the Curt Rail Kit # C16429-204 you will torque all 1/2" hardware to 110 ft-lbs, and all 5/8" hardware to 210 ft-lbs. The U-bolts are 75 ft-lbs.

I have provided a screenshot, as well as a link to the manufacturer instructions for you below. Hope this helps!
