Go to a bearing supply operation and avoid MB. The bottom two bearings are common but the top two would probably need to be ordered.

Thank you for all the responses.

It’s really appreciated.  Is there a supplier anyone can recommend? I don’t have any urgency to get the parts asap. If you have the correct ones to sell please let me know and price. Or vendor.

Any recommendations where to get input shaft shims so I can cut down the end play?

The input shaft needs a bit of end play or the transmission will pop out of gear during deceleration. I used to add shims and sometimes it would work and sometimes it didn't.

 I put everything back together the way it came apart and I haven't had a problem since.

Ok Dan

  I think as I didnt have any shifting issues before or popping out of hear  I will go ahead and assemble as it was originally setup.

Sure, it makes sense. Bearings are precision made and all should be the same size within a very small tolerance. If your transmission was working correctly before you took it apart, it should still work after assembly because bearings are so well made. Make a poorly made product today and you won't last long. NTN, FAG, SKF, and others, are all high quality, dependable product.
