The autoadjusters are available new, but they're expensive. The left always has 1 ring cut near its closed end, but the right may have 2 or none. The screw has L or R embossed in its unthreaded tip. The unthreaded cap has 3 rings or none, and fits L & R. There is also a very small, thin washer between that end and the wheel.

Right Adjuster Kit
MotorCraft BRAK2545AThe other parts shown (and the e-brake levers & piston pushrods) are NOT available new.
Now that these factory-original parts have been thoroughly cleaned & painted with high-temp paint, they're probably better than new. But I'm not applying brake grease until I'm ready to install them.
