Scenic cruiser wiper part

[olbugga]

I Took my windshield wiper arms off in order to do a better job of polishing, and found one of the tapered, knurled fittings that adapt the wiper arm to the linkage shaft broken, and naturally it won't go back on properly. It's a pot metal piece, round, tapered, with splines on the outside surface to mate with the wiper arm inner splines and a hole in the inside that mates to the motor linkage shaft. Now, if any body reading this has trouble with this description, just try and imagine the trouble I had in coming up with it. In any case, any idea where I can find a replacement ?
Thanks in advance for ANY help.

Had the same problem! First there are 2 Sizes 3/8 and 5/16 ! They are available from School Bus Parts On Line! Great people and reasonable prices! I ordered 4 so I have spares! I believe that the 3/8 will be the right ones for You! They are Color Coded so phone while You have the Old Part in Hand! WM4A Knurled Driver should be right!

I would think you would be able to get them from large truck parts houses also. Even the big NAPA stores may have them; at least can get them.

Mike,
I thought that too. However I tried several places unsuccessfully.I did find the smaller 5/15 Drivers but never the 3/8 size!
SBP On Line is a simple phone call away-Inexpensive and great service!1-888-769-7769
