Here is a new aftermarket bolt kit for the Western Unimount (Mount box assembly part number 63300, model 3515) for a 99-06 Chevy/GMC 1500 pickups. The Western bolt bag kit for this mount is part number 63335. All hardware is new. Western does not include the 2 bolt bars/bolt on a handle (item 6 in diagram) in the 63335 bolt bag, but they are included in this kit. These are the bolts you would need to bolt mount together and to the truck frame. This kit is just what you see in the pictures, it only include items numbers 6, 8-13, and 18 from the diagram and list in the last picture. Do not expect to receive any hardware/parts that is not included in item numbers 6, 8-13 and 18 from the diagram and list in the last picture. In this kit, item number 8 (plate frame) is replaced with 2 washers for each side (1 plate frame= 2 washers in this kit). The Western 63335 bolt bag includes other parts associated with the link arms that are not included in this kit. The finish on the hardware you receive may be different than the finish on the hardware in the pictures. The last picture shows the Western mount diagram-make sure it matches the mount that you have. Thanks for looking and feel free to ask any questions.
