Which parts you talking about? The upper frame bars differ from the rear tank mount to the back. So side panels, seat are a no go, but the rest - sure. Well the footpeg mount area is different also, but that's just the peg area. The pipe mounts wind up in the same location. The SC has the aluminum pieces to make it look different, but all roads lead to Rome in the end. But most of the parts are interchangeable.
I have both a 1981 K and a 1982 SC.
If you can wrestle the left hand side case for the SC, I'd love to make an offer on it.
