I recently purchased a pair of MOPAR OEM sidebars for my 2004 Wrangler Unlimited. You can see them here. I don't see any way to mount these, in fast the holes appear wider than my actual frame. Does anyone have experience with these? Anyone have them installed on their 2004,2005 or 2006 Unlimited? I've got the sidebars and the bolts - anything else? Thanks!
