Well it all looks very similar to my 300D I must say - thanks for the pictures folks - I too am trying to remember what the heck I did to change the belts on mine...
...unfortunately it has been so long since my car has been in one piece and I've done some normal maintenance...

Here are some pictures of how the front end of my car looked before I ripped it to bits
