Designed to work with our welded Aluminum Hot Rod Bomber Seats. 1-1/4-inch dimple die holes for weight savings and traditional hot rod looks. No pre-drilled mounting holes to attach to bomber seats. Bolt, rivet, or weld brackets to your bomber seats. Floor mounting flange pre-drilled for attaching hardware (not included) Rounded radius matches our Aluminum Hot Rod Bomber Seats. Minor trimming or modification may be required on other bomber seats. Aluminum Mounting Brackets That Look the Part If you are installing a set of our Aluminum Hot Rod Bomber Seats, either the smooth back bomber seats or the lightened bomber seats, these seat mounting brackets are sure to help you get your seats mounted just right without any hassle. Constructed of .100-inch aluminum (that is just shy of 1/8-inch thick for those that prefer fractional measurements) and dimple die stamped for strength that matches our lightened bomber seats, these seat brackets are 10.75 inches long and 8 inches tall. The material is easily trimmed for any seat mount configuration you may desire, as some modification may be necessary depending on each individual installation scenario. These Aluminum Bomber Seat Mounting Brackets can be secured to your bomber seats via rivets, nuts and bolts, or they can be welded directly to the bomber seat sides once you have properly configured your seat mounting location and seat angle. Due to the many variances in vehicle mounting and seat position we do not drill the seat mounting brackets for attachment holes to the seat. Once you have the position locked in for your seat it is easy to mark and drill through both the seat and the mounting bracket if you are not planning to weld them together. These universal seat brackets are not designed for the Aluminum Hot Rod Bomber Seat DIY kit, but with some minor modifications may be suitable as custom seat brackets for mounting this style of seat as well. Our steel Adjustable Seat Riser seat brackets may be a better choice for the rivet together DIY seats.
