			I don't think that 1207 bearing will fit..... 
 
The GM tranny bearing as  SOLID STEEL ( bearing race) insert that slipsover the countershaft..... and is not included...... when I sourced the same bearing in Ottawa the insert from the old bearing was a few mil to big or too small and would not fit the counter shaft. 
 
If this is an issue I will go back to my parts box and measure in mil. for accurate slack........  I still think it not readily avaialble in North America.... nbow in Europe I believe Alex or someone else fround a suitable replacement. 
 
Cheers 
 
PS......Will look for pictures of original bearing in my files.
