do you need more DOWN force against the window ?
or does the wiper (blade) give enough coverage over all
when it wipes the glass ?
you could look for a shorter spring (would give SOME more
down force against the glass) but it might be TOO much
pressure at of the ends.
a longer wiper blade is easy....buy a longer refill @ wall mart
or some place...but id measure the existing blade and look at
the sweep across the glass to try and figure out what the
maximum length is w/out running off the glass and onto the paint.
i DONT recommed cutting the spring, if i had to go this route then
id look for a shorter replacment (sears hardware, tractor supply or
a truevalue store typically have LOTS of different types)
