My rubber mounts are Freightliner truck grille mounts. I payed like $14 bucks for all four. Most trucking places should have them in stock. My throttle servo (Hitec 225 MG) and smoke pump (Sullivan Skywriter) mount on the plate behind the rubber mounts. Loctite will be used all around, except for the aluminum mount to the firewall. Those are nylon locking nuts.
