Will an 85 take an 86 rear sprocket?Yes, but you'll need to switch to countersunk style sprocket bolts.

Excellent. That's what I needed to know. I could only find Sunstar would make a direct replacement for the 85.
What about the rear brake rotor? Are they the same between 85 and 86?

You can't use the '86 countersunk bolts, as they are a larger diameter. The bolt holes in the '86+ style sprockets will be much larger than the '85 bolts, but the countersunk holes will keep everything centered up correctly.
