Cleveland Brakes - back and pressure plate

I'm trying to find the part numbers for the Cleveland Pressure plate and Back plate. I basically want to have two spare sets so that I can pre-rivet pads on to them and have them ready to go when I need to do a quick pad change.

AC Spruce are asking for a part number but the plates have no ID on them that I can see. It's for a 2003 RV9A.

Thanks in advance...

This is likely your brake , but confirm visually
