Hey guys! We recently released our bolt in Kirkey seat mounts for S197 Mustangs. These bolt directly into your factory mounting locations and are modular so you can adjust the seat to just the right position before you finalize your installation. If you have ever had to make your own seat mounts you know how much time this will save you! They are also very light, weighing in at less than 6lbs per seat with hardware! Here are some shots of the seat mounts and an installation video to show how easy they are to use. We strive to make high quality American made parts that help make your race car life better!! I hope these can add some value to your race car build.
