I made mine from a piece of 12" x 3/4" board that is held on by two clips and two 1/4" bolts through the rack. Five minute job to fit/remove. Made mountings for lever 12ga and Marlin lever rifle, fire extinguisher, air horns (to scare up game), fold up gun rest and spare shell holders. There is a 2 gallon water tank (white PVC pipe which stays on bike when gun racks off), a short handled shovel and fold up chair in behind the bush guard.
