Brake Rotor Options (XJ550 and others)

I’m looking at brake rotors on MikesXS for my 1982 XJ550. When I filter by bike, only one part comes up (#MD2023RS). However, they sell several other rotors that look like they should fit, but aren’t labeled as fitting. Can anyone confirm that this is the case? They appear to all have the same 6-bolt pattern and are listed as having the same diameter. Really it looks like a lot of Yamahas from the mid-late 70s to early-mid 80s use this same style of brake rotor, at least on a visual inspection from pictures. Part numbers from their website below:

MD2023RS

LAMD2024

30-3065

 

For future reference or anybody who finds this thread, I’ve attached some screenshots of my correspondence with MikesXS. It appears that the rotors could be interchangeable, but that they cannot give a definite answer. They explain the reasoning for having different part numbers for rotors that appear to be dimensionally identical as well. I have some emails out to EBC (the manufacturer of some of these rotors). I’ll update this thread if I hear back from them or find anything else.
