Rear Disc Conversion 82 Cb750K

Hi guys,

I'm currently working on an 82 CB750K project. In the process of converting the front end with GSX forks and brakes, and figured I might want to do an upgrade to the rear brake as well.

I know the super sport had rear disc and was wondering what I would need to do in order to do a swap. I found this "kit" on ebay, but it's from a 78, and the comstar rim won't match the newer model comstar I am using in the front. http://www.ebay.com/itm/291894272061?item=291894272061&viewitem=&vxp=mtr

Right now I'm not sure where to begin, or what my options are. This would be my first time doing this, but I'm pretty deep into the project and not afraid to work for it, learning in the process from the great builders on this site. Any and all info or guidance is most appreciated.

THanks!
