Need to figure out what rear disc brakes I need?

[RonC23T]

Hello, I recently bought a 23 T bucket. We noticed brake fluid on the rear drum. I need to figure out what the rear end is on this car to figure out what disc brakes I can buy. I was told it was an Olds with Corvette brakes. Where can I look for markings or how do I tell what it is Thanks. A new T bucket owner.
