On the rear windows, you mean the chrome trim is not there

just "cal look" rubber ?
The front windows scrapers come with the chrome. If you do not want that look, some people try painting it black but I don't know how good that would hold up

On one of my cars I took off the chrome part of the scraper, I used the inside metal piece from the original one (as it is thicker) and rivited the rubber scraper to it. I think I also had to use 1-2 screws to secure it to the door. Lots of work

trying to make it work but gave me the look I wanted at the time.
