I'm thinking of reverting to a suction wiper setup but my windscreen frame is the later type without the vacuum tubing and with the mounting holes for the electric wiper in front of the passenger. Would anyone be interested in swapping their earlier windscreen frame with provision for the vacuum tubing and a centrally mounted wiper for my later one? But it would need to be the interim type with the strengthened side supports and not the very early one which didn't have these supports.
