Rock slider install Q's

[Marlin]

Does anyone know the bolt sizes and thread pitch, as well as drill bit size, for mounting these to the frame and pinch weld?

IIRC, they are the same bolts that the skid plate uses, just check on Isuzuparts.com. The ones from Rocky road came with some big self tapping bolts, just drilled out like a 5/8 hole and then the drove the bolts in with an impact wrench.

As for the body side, they were like 1/4" bolts, something small like that.
