I'm trying to bring my '83 300D Euro beast back to life, but it's missing the brake booster vacuum line. I had traded the car to a friend for the '78 300D I'm in now and he eventually just gave me back the car but not before pulling some parts out. The one in my '78 is the wrong size so I pulled one from my friend's '81 which doesn't seem to fit in either car. With further investigation I've discovered the Euro models had a totally different hose, but so far I haven't been able to find a supplier or a part number. My car is chassis code 123.130
