The Unibody Plate Mounting Brackets allow the Restoration Rotisserie to be secured to the vehicle bumper mounts or subframe. These are large flat plate brackets with a very broad range of applications where the bumper brackets or frame horn mounts will stay in place for the restoration. Installation requires drilling to match the bolt pattern in your application. Most full-framed vehicles will require no addl brackets other than the mounting that comes with the Auto Twirler (brackets are normally for unibody apps).Unpainted. One year manufacturer's warranty. Made in USA.
