Hi guys,
I work for Hella and Bosch in Norway, so if anybody has questions regarding replacement parts from Hella or Bosch for your Spider, I am more than happy to help.
I don't think buying parts from Norway is a good deal , but if you need part numbers etc, I probably can help you.....
I will soon post a cross reference list for Hella and Bosch parts that I made for my -82 Spider
