Pulley for a 5/8 belt on a GM alternator

Did a search and came up empty, I need a pulley for a GM alternator for a 5/8 belt. I know people have run these alternators on older cars with the wider belt and am hoping someone can tell me where to purchase the pulley. Thanks for any help.

I put a narrow one on the lathe and made it fit the 5/8 belt

If you have it, I've used the original generator pulley on some.

 

I think the old lincoln sa200's ran a 5/8 in belt. So it maybe as close as your local welder repair place.
