Is this something that I can have produced for my caddy? Who should I be in contact with?
EOS GmbH Electro Optical Systems --3 years ago
We are happy to support you with your caddy project! Please contact us via soicalmedia[at]eos.info and we will provide you with contact details.

So it's three years old. Their CAD files and print output should fit any Mark I Golf. Why aren't they at SEMA?
