I have a 2005 montana sv6. Needed the rear wiper motor replaced. I ordered one online and when installing it, noticed the threaded shaft that goes to the outside uses a nut with a type of bushing on it. The threads on this are bigger than the original and I have been to every parts store and hardware store in town and we can't figure out for sure the thread size and pitch. The only way to get this nut as of now is to return it and pay double at a parts store here in town since it comes with it on theirs. Anyone know the size of this or where I can buy one? Thanks

Just a thought, could this possibly be a left-hand thread.

It wasn't on the new motor I looked at in autozone.

You could take it to your local Home Depot and figure out the thread size and pitch in their sampler demo bolt/nut size thing. They have metric there too.
