[GreenKeys] Part help

[Til128 at aol.com]

Hi all:

I am looking for some help locating the following  part:

93107 - Bearing, ball

I need 2 of them to replace one that  froze up on me.
If one goes the other can't be far behind.

This is  used in the 3 speed gear shift for RO & KSRs.

It is the Early Design  part.)

It can be found on Pg.56 of 
Bulletin 1149B
Section  573-116-800TC
Issue 1, June, 1965 
 
I have looked around and it seems like this is the only place this bearing  
is used.  :-((
 
It is not a "stock" bearing, so I can't go to my usual bearing  supplier.
 
Any help would be greatly appreciated in finding this part.
