Needed to remove the diff to take out the prop shaft (long story) to find the upper mount bolt utterly jammed into the RH metalastic chassis bush which would have been understandable had the car done a few miles but this is a new build (hence long story). Resorted to the Dremel to remove the bolt head and then drew it out with the nut and an increasing stack of washers whereupon it jammed in the LH bush this time needing a length of ali tube to draw it out. Ran the micrometer over the bolt and the head end of the shank is +0.6mm over the rest of the shank. So, moral of the story is run a micrometer over the bolt before you hang the diff on it to save the subsequent grief.
