I was pre warned the latest job may look a small one but is a pig to do. In my defiant mood I took it on. Removed the front cowl, took out the wiper motor which involved
disconnecting all the linkage. Thank goodness for mobile phone cameras to take photos of what goes where for the refit. 50 years of being in situ for the parts was a challenge to remove and refit, Anyway after a good polish on the wheel, paint and a few new bolts she went back together this evening.
Before and after photos below.
