Anything's possible...  ;-) Of course it could also have been 
changed by a PO.

The Wolfsburg is a well known mid year change, I don't know about 
the heaters, but there are LOTS of examples of mid year changes, 
some better known than others.

I THINK it was to reduce vibration. The later mirror has a shorter 
stalk so its resonant frequency would be higher. I suspect that the 
long stalk vibrated badly at normal engine frequencies if not braced 
and this was annoying.

A side effect of the late mirror with the short stalk is that you can't 
see as far to the rear as you could with the early mirror. I suppose 
this could be cured by lowering the front end.
