We have Adapter plates for Rugged Ridge and Bestop Seats. No Hardware Included.
This allows for you to use the existing seat slider from your factory seat and install a new seat of your choice. The plate does have a slotted hole and other seats may fit, we so far have only installed the two mentioned above and are Powder coated Steel.
For the Roxor side of things, you'll use existing hardware, you will have to get bolts for your new seat if they don't come with them.
These come in a pair, ONE pair will do ONE seat!
