Review on JW Winco 351 1 14 13 10 55 Cylindrical Vibration by John Bailey

I used these little isolators to install a fresh water pump on my 1977 GMC RV. I used a 1/16" aluminum plate to make the carriage mount and then another smaller plate to actually mount the pump. Insulators are inserted between two plates. They are almost inaudible now as the pump is pumping in the car. An excellent improvement.
