I have a 67' Bonneville with worn out neck bearings which was on the bike when I bought it. Can anyone tell me where to get a set of tapered rollers for the setup? If not, how about just a set of bearings and races for ball bearings?

to adapt to timkens, assuming it hasn't been done already

simply requires off the shelf shim spacers for the bearing cups

once you have done that

then all you need to do is match up suitable metric cones, to the cup that will now fit in the frame, having compatible "K" factors

I don't have the bearing numbers to do that conversion, never thought to save them or write them down

but I do have the shims from a batch I had CNC'd years ago

I personally can't stand building a bike with loose ball roller bearings
