I did my bushings and found the shaft was not worn just the bushings .the new bushings i got were oversized and needed to be fitted l spent hours doing it by hand a socket and sandpaper .I tried a wheel cylinder hone and it did not work very well .There used to be two types of bushings oversized and stock size .the old ones were dimpled and the new ones were solid . Worked out in the end lots of elbow grease without proper reamer tool
