John,
Got your message last night. My wife and I went to some Christmas shows at the Opryland Hotel in Nashville.  Sorry I missed you.

I just got back from the shop and the guy said he can't get the MS194P bearings from Clevite.  He said all that he can find are standard and 010. 

He also gave me a P/N for F-M, 568M.020, but he said his supplier can't get them either.  

He said my best shot would be to find some old stock some where, but I haven't had any luck around here.  Any suggestions?

Merr Christmas!
Kenny
