Rear seat lock pin thread size

[scirocco25 at gmail.com (Eric Person)]

I know this is going to be a long shot, even for those of you that have 
been on the list forever and think they know everything there is to know 
about sciroccos.

I need to know the size and thread pitch of the pins that hold the top 
of the rear seat to the body.  They are p/n 533 885 197.  Bentley doesnt 
give me the size, which I assumed they wouldnt.  It looks to be 
measuring out to be 1mm thread pitch, which sounds right since its a 
fine thread, but thats measuring with my ghetto amerian ruler.  Its 
measuring around 11mm diameter also, but that isnt a very standard size, 
so its more likely a 12mm.
Who's the ultimate scirocco nerd on here that can  give me the right 
size?  :)
