Autodoc might let me down so maybe I'll get new bolts and wait a few more days.
Give it a good wire brushing first. Ive done two sets of rear shocks now and the bolts all look rusty, but came out no issues. Brush the threads, undo them s little bit , tighten them up and more WD40 job done.The head of the bolt on mine is in very bad condition and the nut is the same. Surely it would be better replacing the bolt?
