HotSpring Spas - Parts - Moto-Massage - If you have an older Hot Spring Spa (1985-1987) then you will need this entire kit if you have never replaced the Guide Body in your spa. If you have replaced the guide body then you can order a stand alone Moto Massage Assembly. If you have replaced the ORIGINAL Moto Massage assembly then more than likely the guide body has been replaced. Please contact us for further assistance.
