If you are looking for an off the shelf kit, Early V8 garage has bolt-on (no weld) kits that include a master cylinder as well as mounting brackets. Single pot or double pot master cylinder options. Kinda pricey but thought out well.
I have one of their kits in my 34 pickup with a single pot mc which is the 39-48 ford mc.
