73 Duster Wiper Linkage

[silentdub]

Hey folks, don’t get to work on these often but this vehicle is in need of a wiper transmission. The motor is working but the linkage isn’t moving, looks like a trans issue.
Before I start taking things apart as it is under the dash, Can anyone point me in the direction of a restoration supply house that may have a new assembly?


Appreciate the feedback

Is the shaft on the motor turning if you disconnect the linkage? If not probably wiper motor needed.

I doubt you need a new assembly if the motor is turning. My money is that the cross-bar fell off the arm. It is held on with a really weak plastic ring that snaps on and transfers the motion to the wipers. Get ready for some uncomfortable positions to reach up under the dash and reconnect it. I usually get the center one from going in where the radio is and the drivers one you can reach under to the left of the brake pedal.

The plastic bushings are similiar across years and i think I made the following one work for me.

The plastic bushing are the point of failure but wear in the pivot posts is a major factor (especially left since it also carries the right pivot). Go ahead and service reseal those while at it or the new bushing aint gonna last 2 years. Learn from my experience now or later? Wanna know all about servicing pivots?, Just ask

I had the same issue with my wipers, replaced all the nylon locks. It was easy to change the one from the motor transmission bracket nylon locks with the windshield out and drop the dash. Otherwise, you can try to do it through the glove box and radio removed. It won't be easy.
