Projects Master Cylinder ID

Hey guys, I have these two master cylinders, they are FOMOCO off of a Hot Rod that hasn't been touched in 40 years. We're trying to identify them to either rebuild or replace with repops. They have A215 or A216 cast on the sides with USA and a number 1 under that. Bolt spacing measurements are pictured. Thank ahead for any insight!

Looks like a 59 Ford type master cylinder
