Looking for suggestions how to find older Quantum parts. Specifically, looking for drag washer part number HV4059-01 for 2008 model Quantum Accurist AC500PT. Quantum's website and retailers I found post a message saying: part is unavailable.. or, no longer available. I also tried eBay and Amazon... no luck.

I plan to call Quantum's customer service Monday.

Thanks for any advice.
