AC disk gang bearing?

[deerly parted]

I think I have an AC wheel disk. I need a gang bearing assembly on the rear gang since the old one is completely gone and suspended with a chain. Are there any sources? No paint left on old disk so is there a way to be sure its even an AC?

Here's a link to my method of rebuilding the old allis chalmers disk bearings

If it is an old Allis disk it has balpak proprietary allis bearings. These are about $250 from AGCO. If you want to do a little work you can rebuild them from the article above. If you have any questions just ask.
