I'm assuming that your car looks like a North American S-Class car, example the 1984-1985 500sel . If that's the case then it should be a W126 body which was produced from 1980 -1991.
The engine should be a 117.- - -
I'm not sure what the last 3 are, because it's probably a grey market car.
A W107 is for a 2 door convertible "SL" or a 2 door coupe "SLC"
produced from 1971- 1989 and the 116 engine code does not seem to be one that belongs to a 500.....maybe for a 280, 300, 350, 380, 420, but not a 500.
Again I'm not 100% sure, but that's my understanding.
