Hi TCK,
I've used this needle roller thrust bearing from Simply Bearings on my M32, so search for this and see if it's the business.
NTA2840 Needle Roller Cage Thrust Assembly with 2 TRA2840 Washers 1.75x2.5x0.1406 inch. Other sizes are available.
I needed to make up a bit of space, and found that, of all things, digger bucket shims come in different thicknesses, so with a selection of those a solution can be made up.
Cheers for now
Doug
