I had to put my stuff into a new windshield frame( due to rust). Anyway, as good as I can remember, once you fold down the windshield, you'll find two oblong holes, one has your wiper motor in it. There isn't enough room to play around in there, but I wouldn't imagine it would be very hard to change out one of the linkages, if need be.
