'82 850GL rear brake rotor

[Tindjin]

So need to replace the rear rotor on my new to me bike. The inside of the rotor has been metal on metal with the pad' for probably a while. What other years/models can I search for that would be the same part?

Bike bandit was $370 (WTF?!) for the part.
My local shop can get one in for $150.

I'm trying to find one myself though. Ebay has one from a '81 850GL, anyone know if it's the same?

I'm trying to work through parts list to see if it's the same part number but it's slow going.

Thanks in advance.

ETA: Ps.. I did a few searchs for rear rotor including model and year changes but didn't find anything diffinitive.

Looks like about any 82/83 G or GL model will work. E-bay is probably the best place to look. Just enter the part number here
