Wiper Linkage Arm Bushings

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.
