Kenny's suggestion is the easiest if someone would buy the DPOCV. I will try Cocres idea though (if only because I'm mad I didn't think of it myself. New top link will be from CCM NOT Surplus Center. As to 'beenthere's comment on 'why should they stock part'- not everything they sell is surplus- parts are a big part of their business! I wasn't asking that parts were in inventory ,I was asking for a solution to a problem and they refused to help. That seems like poor customer service. Maybe it was just the one tech employee, I don't know,\; but I do know I can shop elsewhere.
