You don't want them too soft. There is an old post -- maybe 4 or 5 years ago -- by Owen_Dyneto where he was having issues with those same bushings. His issue was with some from Steele that did not last very long. He compared hardness of Steele's to a NOS factory bushing and found the factory bushing to be much harder. He published the results and way he measured using a method he was able to come up with. It was not really precise by usual methods and standards but did give a comparable result so he posted his findings. You might search and see if you can find his info. Maybe you could use his method to test your new bushings.
