Hello,

I am new to the boards and was hoping someone could assistance me with an issue I have with my 1975 F250. I’ve been trying to find a replacement wiper arm pivot nut (the serrated nut that the wiper arm attaches to). I pulled off the old one because the grooves were worn. I purchased a new wiper arm from O’reilly’s Auto Parts for a 1975 F250. It came with a new pivot nut but it doesn’t fit on the wiper pivot shaft. I went to a classic truck auto parts store and have looked online but can’t find a replacement anywhere. I thought this was going to be an easy fix but apparently this nut isn’t sold separately. Any advice would be appreciated as this is the first truck I have ever owned and worked on.

Thanks,

MC

 

You need the splined shaft that the wiper arm attaches to? If that's correct, I've got a parts truck I could pull them off of. I'll have to check to make sure they're in good shape. Wipers are still on it.
