Should the inside of the windshield wiper mount be splined? If not, is the position maintained only by the friction pressure from the nut?
Seems like there's a chance it could flop around a bit and lose position without a spline fit.  |

So there should be splines?
The picture is from a new URO part. Both left and right wiper fittings are smooth. |
