Rear brake drum compatibility

[jcbfrsr]

Hey everyone, I have found a rear brake drum on eBay, "1980 Yamaha XS400/80 XS 400 Rear Drum Brake".
I am wondering if this would be compatible with my 82 XS 400 SJ.
Also what other years are compatible? I am looking for a rear wheel as well so if it's more about matching wheel to brake than brake to frame that would be cool. Thanks for any help

The 76-77 xs360 and the 77-82 SOHC xs400 all used the same rear drum brake shoes.
