After 51 years. My wiper bushing finally broke at the motor arm. Found nothing left of it to compare a new one to. Does anyone have a part # for the nylon bushing? Yeah! I know good luck finding one. Right? If so, has anyone replaced this piece? Just curious how much trouble is it to replace?

51 years ago is a 1974 model car. 1974 A-bodies used polyurethane bushings, or retainers, on the wiper linkage, which first appeared on the 1973 A-body and B-body models, then spread throughout most product lines in subsequent years, continuing through the 1990s on some models, including trucks.
The bushings were not initially serviced separately, but were later released as Chrysler number 3799089, or the revised number, 03799089. These bushings are still available through Chrysler.
These are the small linkage bushings, not the motor drive cam bushing part. The cam bushings can be found as listed in post #2 as well as the small linkage bushings.
The Chrysler 3799089 bushings I have used are superior to aftermarket bushings that I tried, such as Dorman/Help! number 49440. Note that the Chrysler bushings contain white lithium grease. The aftermarket may not. The Chrysler bushings are polyurethane, and specify/use lithium grease.

What year?? '74 is a guess since you did say 51 years old, but still...
There's two different styles, '68 - '72, and late '72 and up.
Be wary of the el cheapo EBay and Amazon ones, they don't fit worth a sh#t.
Dorman makes good replacements (look in the "Help" section), and last time I checked, you could still get the late ones from your local Dodge dealer (cheap) since they were also used on later trucks and miscellaneous cars.

Got that information. Thank You!
If you have the Chrysler Service Manuel for 74, it will help you. I did it a couple times, and many people will give you the wrong advice on how to do the job; hence, the Service Manuel. It helps to take the front seat out. Under hood, the Wiper Motor can be loosened and tilted back from the top. Then you can access the nut the holds the arm that's difficult to get to. The arms have to be removed, and then you pop the new Bushings in.
Thank You for the advice. Would you know if all the bushings for the whole assembly are the same part # ?. One post led me to believe the motor drive bushing was a different part #. Please Advise.
So I was able to remove the instrument panel for better access. I found this # on a original bushing still intact on the drivers side wiper linkage. Does anyone know if this is a good mopar part # ? Something I should look for when shopping for these parts?
I believe they are all the same. In the post above, the Mopar Bushings pictured are the ones you want.
The 68 thru 72 linkage I have on hand for my 67. 67 and earlier have bronze bushings everywhere. Only point of failure is the special pitman arm bushing. That type can get noisy er with age. Plastic is quieter and serves as a point of failure.

I picked up a spare set of links from a '72 at the boneyard a few years back, those plastic bushings are the bane of my existence. I'm hoping I can use them in my '75. I used to have to reach through the radio hole and run the wipers while I was driving my Valiant.
I went to drive the Dakota around the block a few weeks ago and clunk. No wipers. Those wipers have never even been used since I did the bushings, and they were Mopar bushings. I used silicone grease (SilGlyde) but will use the stuff recommended here. Silicone doesn't usually attack plastic that I'm aware of.
I'm at the point where if I have to spin up a bunch of brass bushings and re-engineer the entire thing, I'll do it.
Well! Success! I ended up removing the entire linkage assembly. The more I moved it around while it was in the car. I found more of the bushings disintegrating. I removed the drivers seat and the instrument panel as suggested by a couple of you guys. This worked the best for removal of the linkage and wiper pivots. I was able to purchase 4 new bushings and the wiper pivot seal kit from the local Mopar Restoration Counter at a local dealership using the part # that was posted. After cleanup of all the bushing posts and wiper pivots. I installed the 4 bushings with white lithium grease and snapped them into place using the technique suggested. Installed the new dust gaskets and seals on the pivot posts. At this point I taped the linkage together to prevent it flopping around and stressing the new bushings while sliding the whole assembly back into the instrument panel opening. Aligned the wiper pivots and tightened them down after centering the pivot seal in the holes in the cowl. Removed the tape holding the linkage together and attached the motor drive arm on the motor shaft. I tested the operation of the linkage before reinstalling the wiper arms. All worked as designed. About a 2 to 3 hour job to reinstall the linkage and make eveeything operational. (moving slowly as not to screw it all up) so Thank You to everyone for the information you guys posted with part #s, and installation tips. Much appreciated. No worries taking the car out now in threat of wet weather.
