Just got one myself to do a change from M to solid aluminum. Nothing like having the right tool for the job. I originally installed the M using the makeshift method and wasn't looking forward to doing it that way again. This tool extracted the M bushings effortlessly and pulled the the Turner solid aluminum bushings (which are a serious interference fit) in with the help of a good long breaker bar.
