Once I strip away the sides and gate I imagine I can pull the bed off the vehicle and turn it over to create a template. I hate to pay the price that Kubota wants for a new one and have not been able to find a serviceable used one.
Use RTV to muck horse & alpaca stalls. Dealer never recommended spray on bedliner although I did have the camo composite one. Completely rusted through including rear horizontal support beam.
