Neat job Dave (as usual !!)
I'm still kicking myself because about 3 years ago at Retromobile in Paris there was a bloke making custom silicon wiper blades for classics. My Mog was a year old at the time, so I thought to myself "When I need to get them replaced, I can get him to knock me up some nice silicone ones". Naturally, I lost his card and haven't managed to track him down on the web, nor have I managed to find him again on my visits to Rétromobile in sub sequent years. Aaaargh.
