TCM fuel conroller parts

I removed the FCU (mixture control unit) from my IO-520-BB due to a leak. I took it to Quality Aircraft accessories for O/H. They told me today that they need a spring, part number 628371, to complete the O/H and TCM is quoting at least 100 days out for delivery. Does anyone know where this part can be found, before I start contacting all the usual suppliers?

Model: Bonanza V35A
Aircraft Serial Number: D-8807

RAM in Tx, High-Performance Aircraft in CA, and Airpower in Tx are all showing good stock on those.
