This is the free (branded) version of my first gen RX7 windshield wiper bushings. They are as close to 1:1 replicas as I could get, and should work just fine for your DIY and replacement needs. The included profile is for Polypropylene filament, which is what I recommend. 

The original bushings were very durable and made out of rubber, so they have just a little bit of give. The PP filament also has a little bit of give, but also comes with the benefit of being very highly temperature resistant, wear resistant, water resistant, and chemical resistant. This makes it a perfect candidate to replace bushings for a location that's going to have a lot of back and forth wear, and be exposed outside to the elements. I have had a pair of these on my FB and they've been exposed out to the elements for the past ~8 months or so now, and I haven't had any deformation in any way. 

The driver and passenger side bushings are labeled for easy placement. If you can't print these parts, or want a pair of bushings without any of the text, I will be selling them soon, so be sure to stay tuned.

Please, I welcome feedback, if you think these need to be adjusted in anyway, I'd love to hear it so I can make the changes. Thank you!
