help ID these mystery willys brakes

I know I said if it ain't broke don't fix it, but, I took it apart anyway. Clutch chattering, oil leaks and steering are going to be addressed. I was looking at the brakes and have no idea what they are. Does anyone have an idea?
I am going to change the steering to a cross steer from the tradional but that will be another story later.

 

I think those are 1968-early 70`s Ford .Fullsize and Mustang,Fairlane look the same but Advance Auto Parts shows different part number.There should be numbers cast into the caliper for exact application.
