Ready to Rack up the Miles

Our Universal Seat Mount Plates are designed to aid in facilitating mounting an aftermarket bucket seat to our Universal Seat Sliders. You can also find these in our complete Universal Seat Mounting Frame and Slider Kit as well, which provides everything you need to mount an aftermarket bucket seat in an early hot rod or pickup truck with a flat style floor.

Depending upon the seat used our universal plates can be mounted with the outer mounting lip positioned up or down to attach to your bucket seat’s framework. The lip features four pre-drilled holes, but there may be some drilling required of these plates or possibly additional mounting hardware required depending upon the seat being fitted. We highly recommend to mock everything up on your workbench beforehand.
