Hello, I have a problem with my 1985 380SE. The nut that holds down one of the wiper arms onto the wiper transmission has worked itself such that it spins in place. That is, I can't get the nut off, but it's not stuck either. Something has stripped in such a way that the nut is just stuck there. I can't for the life of me see a way to get that nut off without damaging the wiper arm beyond repair. I do have a dremel, but a cutting wheel can't do the job thats to the shroud of the wiper arm around the nut. Any ideas on how to get that damn nut off? Thanks, Richard
