Hi Yal,
   I'm running low on fund also, and have been looking
to clean out my basement.  I have a rear wiper unit,
in good working order.  I just tested it. Complete
with all the rods and shaft.  $50.00  plus shipping.
    The motor alone sells for $160.00 part number
is  251-955-713A.               Picture avaliable.
                         Eric
