[MBZ] tool, left side, right side.

[John M McIntosh]

I've tool to adjust an issue with door latch on the w124, but I note  
it's marked L  for left side. There is a tool marked R for right  
side, btw and they are not interchangeable.
Question is from a mechanics viewpoint, is L (left) for driver side?
