I did it on my '99 and the most difficult thing was unhooking and
opening the plastic cover over the nut which fastens the arm.  One
caution - operate the wiper with the arm removed and be sure it is in
the park position before you install the new arm.  When you install
the arm, take care that the arm is not tightly bottomed out in the
support bracket.  If the arm is too tight, the motor may fail to
start.
