85 5th ave, Wiper bushings needed, do they exist?

I found a 5th ave at the junk yard and was going to get the wiper set up.. but there is play at the transmission joint, and where the wiper drive arms attach to the posts that go up to the wipers.

It appears there is a nylon bushing right next to the metal post that does all the work on all three of these joints. Can I get new nylon bushings, or do I need to find another donor car?

Thanks,
Jase
