Fastlane for the fittings...... you'll pretty much have to find someone with the same year car to get the routing right. I think that it's "trial and error" time if you can't find someone with an 80 300CD with a camera willing to snap a pic (an 81 might work too but MB liked to change the vac routing around it seems).
