I went from manual drums to power drums after owning my bird for 2 months. Was the easiest upgrade and had the most impact. All I did was simply add the booster. I used the same master cylinder, brake lines etc. I had the pull and bend the lines a bit but the entire project took me less than two hours and as stated was the best thing I could have done. I then later went on to replace all the drum hardware (springs and brake cylinders etc.) and they work VERY well. I am no mechanic but I did all of this myself and adjusted them etc. and they work great. Good luck!
