Since I go through shafts like food I am always looking for replacements. So far everything has worked. But I remember a site I found a year or two ago that had the specs of the TTB shafts. And I remember the dimensions changing slightly over the years. Like the late 80's shafts being 1/2" shorter than others. Some stub shafts being slightly longer than others, etc. Was I dreaming or is this the case? If it is the case will they still work for me because I don't think they will? Thanks. Posting this on FSB also.
