I haven't tried Sunset yet but all the usual sources (Pelican,AA,Automotion, etc.) The most expensive bearing is the Pinion bearing that seats in the case. There is a guy on Ebay selling this bearing at a huge discount. Any experience with these?

Check carquip.com

Check with Rich at HPH. It's not worth buying a cheap bearing to put in the middle of the transmission. When the bearing goes, it will take out the ring and pinion and cost you more.

Dr. Evil has a good source. They are tip top quality bearings that you can trust. Find him.

It's interesting that Carquip is offering the same bearing on Ebay as the link I posted. It must be a legitimate replacement albeit for a different application (read:not Porsche).

I'll be making some calls but still welcoming your suggestions.
