I was able to remove the old wipe assembly. The splined shaft which is part of the wiper motor is supposed to be visible so the new assembly can be placed over it and then secured with the nut. What I found after removing the old assembly was a larger diameter shaft, not looking like a splined tapered shaft. It almost looked as though it took on some of the metal from the i.d. of the old assembly, consequently, the new assembly will not fit over this enlarged shaft. I can't remove any material from the shaft. I don't want to buy a new wiper motor if I don't have to.

Has anyone experienced this and are there any fixes other than dremeling the shaft down to look like a splined shaft?
