Fits on the tailgate of most Jeeps and newer Broncos. This enclousre does not have mounting holes or hardware for mounting, this one is a "mount it yourself" style enclosure.

We do have Jeep specific and Bronco specific tailgate enclosures that come with mounting holes cut out for placement, as well as rivots, nuts, bolts and mounting brackets. (ex. P110STGB link is here https://bass-maxx.com/product-details/11)
