Okay, I've got a front pair of CUCV shackles that I'm planning on installing on my rig. They have a mount that takes the place of the stock bumper mount. All I should have to do is cut holes in the bumper, which shouldn't be that big of a deal. Anyway, how do the rears mount? Do they just bolt to the frame with no special mount like the fronts? I've searched for some pics, but couldn't find any that showed it real well.
