Need Help! Chick Vise Work Stop Info

Does anyone know where to buy a 5X type vise stop or work stop for a Chick Foundation plate?

I can't find anything and don't have time to make them.
I'm setting up a job where the raw stock hangs over the vise edge 2.0 on each side on X.

I don't want anything clamping to the vise it has to mount to the foundation plate.

Thanks
