Here is a new aftermarket bolt kit for the Boss RT3 (LTA04767B) mount for a 99-10 Chevy/GMC 2500, 3500 pickups. The Boss bolt bag kit for this mount is part number HDW05582. The Boss bolt bag kit does not include item 99 (1/2" bolt puller), but I have included one in this kit. 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 2 pictures show the Boss mount diagram, and are for reference only-make sure they match the mount that you have. You will be receiving items A-O and item 99, as shown in the diagram in the last picture. Items A-O make up the Boss fastener kit HDW05582. Thanks for looking and feel free to ask any questions.
