We scored a complete (but rusted) early CB450 K1 front end for the '77 CB550 Project, Drum's are infinitely cooler than the clunky disc/calliper front end.
Got the polishing Rags out and started on the sliders and Top Yoke, need to get the stanchions hard chromed, then just bushes, shoes and a whole lot more elbow grease. It even fitted straight in.
