        This from a post I sent back in Aug2012

      Regarding the StrippedSplines ~ Drape some SteelWool over the post,

press the WiperArm on & apply your Nut or Bolt ~ works great. I lost my

splines 5 or 6 years ago in a blinding rain in Northern Ill. I pulled in under

the pump shelter of a closed GasStation grabbed an SOS or Brillo pad out

of drawer in my Westy, applied the trick & drove on down the road ~ slowly ~

as I could only see tail lights about 8ft in front of me. It's been working fine

ever since. 

        The more I have thought about it, it may actually have been part of a

Piece of 1 of those Pads from a FloorBuffer as I keep some of that in my VDub

also ~ It just needs to be something that is JustTheRightThickness & Coarseness

to Bight into BothMetals ~ I also have added a "PerfectFit" washer under the nut,

if I remember correctly ~

                                                                ORR ~ DeanB
