Do I need fasteners to install this bracket?

You'll need bolts to secure the bracket to your chassis at the factory mounting points. This bracket does not include hardware — source fasteners rated for your vehicle's weight and suspension setup.

Will this work with my existing seat?

Yes, this bracket mounts any seat that uses standard bolt-down attachment. The bracket itself does not lock the seat in place — that depends on your seat's base and fastener selection.

What's the return window if the bracket doesn't fit?

Test-fit before final installation. Once bolted down, fitment issues are difficult to reverse. If you hit a clearance problem with your specific seat or cage setup, contact ModSupply directly with photos.
