Ford brakes?

I’ve had this car for a few weeks now (69 dart). I was thinking it had an 8.25 rear but now I’m thinking it’s a ford 7.5”. I’ve looked at all the pics online and sure seems like it. What is weird is I bought a new brake cylinder (73 dodge) and it fit just fine. Any ideas on what year and type of car these brakes could be from?
