I removed the old arms and but cannot put the new arms on (the hole is too small). Am I doing something wrong?

Willys Jeep Parts Tech:
Give us a call or email with some photos and we can help you troubleshoot.

These wiper arms have splines but the wiper motor does not. The arm does not slide on far enough to get the nut on. Am I doing something wrong?

Willys Jeep Parts Tech:
Your motor should. Email us what you have there to help.

This might be a tough question but chances are it’s been asked before. During the history of the GPW & MB there was a change from the simple manual tandem lever operated wipers to an upgraded system that used a wiper lock and a tension wiper arm with a 9 inch blade. These parts are difficult to find and there doesn’t appear to be an aftermarket reproduction yet. I found a seller in the UK that has 1/2 of one upgraded side( wiper lock bracket, crank handle and nut. I have pics if needed) I need to find a tension wiper arm and blade that will fit onto the crank handle, does anyone know if the tension arm from a vacuum system will fit on this crank handle? A huge thanks in advance

Willys Jeep Parts Tech:
If you can please email what vehicle your working on there and we can help you out with your wiper motor or manual set up and should have a solution.

Will this fit 1957 CJ-6? Will the majority of parts for the CJ-5 willys jeep also be the same part to fit CJ-6 willys jeep?

Willys Jeep Parts Tech:
Yes, as long as you have the original vacuum wiper motor.

Would this fit a 57 jeep FC-150

Willys Jeep Parts Tech:
Sorry, I do not believe so.

1959 End of wiper motor is tapered and serrated and threaded on the end. Will this arm work? The motor is electric

Willys Tech:
If you have an electric wiper motor its unoriginal. Its tough to say for sure. If you like email us some photos of it.

How long is?

Willys Tech:
These have an approx length of 8.25 like original


Willys Tech:
663367 is the part number for the blade

Will this fit the drivers side of a CJ3B, 1953?

Willys Tech:
Yes, it will work there too if you have vacuum wipers.

What blade does this arm take for proper fit?

Willys Tech:
663367 is the blade part number.

will the old blades fit these arms?

Willys Tech:
Yes that is correct.
