1997 harley sidecar parts diagram

i have a 1997 harley sidecar attached to a 1998 flhci classic. The sidecar axle was drum brakes, but previous owner replaced it with a disk brake axle and wheel. I want to add the disk brake. I have searched online but cannot find a diagram of the parts needed to add the brakes. I am wanting to be sure it will fit before spending a bunch of money. I need diagram for p/n and to see how it all attaches. Any source for this?
