Hi Pharaoh, 
  
Just came across this thread after looking for a replacement horn button inner (also need a door dove tail!). 
  
I am in Australia so would love it if you were still offering to send through the model/file for the horn button, or both. 
  
Cheers, James 
  
ps. tried to pm you but couldn't, sorry - possibly because I've been a member a while without actually posting before...
