Okay. I did not mess up. The company that did the german tape did. Instead of changing the framerate, they just converted it to PAL (altough I don't know if it would have been possible in 1982 to correctly ICTV a 29.976 fps video). So the PAL audio IS in perfect sync to the NTSC video without any further tinkering.
I had wondered about that when you first talked about that, and silly of me for not saying anything.
Glad you figured it out!
