Hi Don't know if you got info on the spacers so here it is
the rear spacer is .687 wide the front one is.500 wide they
both are 1 inch od and .475 id hope this helps you

Hello Everyone,

Looking for a bit of information reguarding the rear wheel
inner bearing race part # 41175-55, which is used in
conjunction with the needle bearing on the sproket side.

I first thought it was the same as the front one but have
learned they are different part numbers. I can make one if I
am able to come up with what the difference is.

Any help would be appreciated and Thanks for your time.
