Dear Sir,
I have an ADL Model 2000M-X heater unit. In fact I have several of these. I have one that has a small problem. The red rubber bushing on the motor side of the blower has become worn out, this lets the blower vibrate and rattle while in use. The blower/motor/heater is all fine and does not need replaced. The customer rep people who I purchased these units from said I must purchase the entire insert unit. The cost is prohibitive and not necessary. Would you please help me get this small rubber bushing so that I may stay a satisfied customer.
