Did mine January, Not to bad to do.
Drum off remove spring that holds shoes to back plate, you can then get to the end of the handbrake cable fit new cable in reverse. Before drum can go back on back of auto adjuster, feed cable through original cable route (note some have been fixed in the middle of the wood floor what fun) on replacement ignore middle fixing as it is held both ends. Failing to back off break adjustment will result in not being able to attach to the handbrake leaver.. Drive car to allow brakes to auto adjust. then adjust handbrake. you will need to do this a few times as the cable stretches.
Mine went in the same place, it is because of the acute turn into the drum, as 4/4 sports have a narrow axel, this is not a problem on wide axel models
