Well I received my rails today, only problem is that only some of the bolts and nuts made it to me.

How may bolts/nuts are needed for install?

Is it just 2 bolts/nuts per support on the rails?

n/m I figured it out.

factory install there are 6 bolts on each side attached to the frame. Only the bolts are removed. 6 bolts on each side to attach the step rails. If you do not have the bolts already attached to your under cab I guess you will have to drill.

thanks, but see post 2
