....The whole point of that recall is to lift the tank... its doing that. Why do you need plastic UNDERNEATH the bolt its not like its going to FALL OUT.
May not fall out IF downward force is constant, BUT in the scenario that the tank gets lifted, possibly by side-hilling on hard snow, or a brush with a tree on side-panel, it is anyone's guess as to what that bracket will do, will it just spin, leaving it turned opposite direction OR allow the tank to slip out of its perch all together..??
