Thanks Zippy!

Here is a quota on Mahle-Clevite website about coated bearings...

"We often get customer inquiries for coated bearings that we do not produce. We deal with three excellent and well-known coaters in the USA and any of the three can meet your needs for a coated Clevite bearing. They are: CALICO Coatings in Denver, NC, HM Elliott in Mooresville, NC and POLYDYN in Houston, TX. They all can be accessed via a web search. Tell them they were recommended by MAHLE Aftermarket Inc."

Anyone ever tried this process? I guess it won't help in the limited size availability.
