Here is a new aftermarket bolt kit for the Boss RT3 (LTA04766) and Sport Duty/HTX (LTA09703) mounts for a 99-06 Chevy/GMC 1500 pickups. The Boss bolt bag kit for this mount is part number HDW05581 (both mounts use the same bolt bag). All hardware is new and meets or exceeds the specified requirements from Boss for the hardware. These are the bolts you would need to bolt mount together and to the truck frame. The finish on the hardware you receive may be different than the finish on the hardware in the pictures. The last picture shows the Boss mount diagram, and is for reference only-make sure it matches the mount that you have. You will be receiving items A-K as shown in the diagram in the last picture. Items A-K make up the Boss fastener kit HDW05581. Thanks for looking and feel free to ask any questions.
