I wonder why it wasn't used on w123's originally. Fuse box cover is easier to remove too. The only thing I don't love with the install is the large vacuum line is now too long. I had to buy a new one a couple years ago so the plastic is not brittle so maybe I can cut it to take some length out. I'm guessing the line can then be heated and slid back over one of barbed fittings?
