2 speed & 3 speed wiper motor arms

[Richie]

Hi everybody:

Is there any difference between a 2 speed and 3 speed wiper motor arm in a 68 Coronet?

 

[RR Fan Dan]

Yes, and good luck finding the linkage that holds them together. You might have to fabricate that piece. It was 10 years ago when I changed the 2 speed to a 3 speed in my 68, I can’t remember all the details because I am getting older and have CRS syndrome, but I do remember they weren’t the same and the parts were hard to come by and one part in particular I couldn’t find so they never worked. I only changed to a 3 speed because I installed the Ramcharger Air Grabber and it doesn’t fit with a 2 speed motor.

That’s good, cause the parts weren’t cheap 10 years ago.

Here is a pic of the difference. They are clocked different and the bushings are different as well. Not sure which you need but I think I still have the 2 speed one

The actual wiper arms are the same, the drive arm & linkages are different

Is the 2 speed the shorter one?

 

[Sixpactogo]

Yes. it is a bit shorter. It is the upper one with the black bushing in the pic . PN 2631794
I just checked. I still have the 2 speed arm along with both interface arms but no pivots.

I think I found one. I don't need it for a few years but I'm a big worry wort.
