CB350 Dual Disc For Dummys?

I have searched here and many other places for a how to guide to putting a dual disc setup on a cb350, but I have had no luck. I know this is probably a fairly common upgrade for these bikes but I have no idea exactly what the process is or what parts are required. Most of the posts I have read say you can use cb550 triple trees/forks? but since they didn't come with dual discs I still don't understand how they work.

Can anyone lay it out for me? Go ahead and assume I'm a dumbass (I'm sure you will anyway). Or point me to a post where my question has already been answered.

Thanks!
