Second option would be to get a ‘almost’ the correct sized shim
Then grind down to fit
vvvThis is a handlebar shim I used for 20yrs before my rebuild (I had to go riser bars because of my neck)

3rd option would be a machine shop
Easy project for them
Hell, they might have a perfect sized car crank shaft bearing in the bin!
