I know i have to punch out the rivets and use the supplied bolts, but whats the torque spec on these bolts? Do you just crank on them until they feel tight or impact them in or what?

 

I think the instructions on mine said 14 ft-lbs or something, but the nuts were prevailing torque nuts anyways, so I just tightened them until they felt "right". If yours didn't come with prevailing torque nuts, you might put some red loctite on them or something just to make sure they don't back off.

The nuts/bolts are a bit too small for me to feel comfortable zipping them on with an impact wrench (unless it was a really small one).
