Steering stem bearing

This is my first post on here. I have been reading the forum getting information and I can not find an answer to this. I picked up a 1997 TRX300 2×4 for $100. It had a broken rear axle. Tore it apart, replaced the axle, seals and bearings with help from the site.

The bearing at the end of the steering shaft is gone. I can find the bearing online, but I was trying to get one locally. The local napa can order me one, but I was trying to get the bearing dimensions and see if they had one on hand. My issue is I cannot find the dimensions anywhere. And the napa couldn’t find the dimensions either.

Thanks for the help.
