John Deere B Rod Bearings

I'm putting gas pistons in my 1945 John Deere B. Just took the old pistons out and my b has insert rod bearings
#2180 CP
FM
PF
on the pulley side.

On the fly wheel side it has
#2180 CP
FM
66
and
2180CP
FM
54
bearings.

Also on the flywheel side the connecting rod has shims, castle nuts and cotter pins. On the pulley side no shims, and lock type nuts with no cotter pins. It has been this way for the 40 years that I have had the tractor.
I didn't think that shims were ever used with insert bearings and the different rods confuse me.
Where can I get new bearings as these are worn and will I have any problems with the different rods?
Thank You for any help or info you can provide..
 
Look at the insert bearings in the model 50 parts catalog. If you have a rod with inserts and shims then it could be a old Babbitt rod that a machine shop modified to accept insert type bearings. I had some done that way and they had to use the thick shim but not the rest of them, to make it all line up correct.
 
I was told the 2180 CP bearings are no longer available. I would like to find out what bearing replaces or substitutes for it.
 
JDBRIDER YT has them listed. May want to check the bore of the rods. Lynn
