I did a search. For the most part I just found people with cb750k's swapping the rear disc brake from the f's onto their bike which makes sense. I just picked up a 1975 cb750f rolling frame and motor but they had swapped a k series drum brake onto the back. I have the rear brake linkage, pedal and a bracket that looks like it will bolt to the frame. But does anyone have information on what else I am going to need to make this work? Spacers, how to mount the pedal bracket to the frame etc.
The '75 f series rear disc brake seems to be a bit too pricey for me so I'm hoping to make it work with the drum rear brake. Also, if anyone has done this photos would definitely help. Thanks.
