Rear Window Wiper...

The problem with that is that the mount for the rear wiper is such as it is You would be better off looking for a rear wiper arm with a longer blade assembly on it I haven't really thought about this is I haven't turned on the rear wiper in about 10 years but anyway I would think that could possibly be a thing but finding a wiper itself to fit on the mount that we have and say even 15 or 14 in might be a stretch I have replaced my rear wiper once on all the Gen 2's that we have but we never use them I hadn't really looked or thought about another assembly but I would look to change probably the arm with blade from some other car or whatever could be worked at which may be tricky because of the angle and offset but should be doable If I see anything when I'm out and about looking in the junk yards I'll make a note of it but I would think a lot of imports with wipers and rear windows and similar fashion and angles there should be a few choices The mounting cone that the arm drops on and the nut screws too is fairly standard.
