Hugo has said for a long time that (in theory) the CAD material for the metalwork should be available.The Mk1 connector is an OTS from Farnell, and is still available. Wiring harnesses are not that difficult to put together.

I have a guy here who can water-cut and fold 1 mm stainless steel - so the only question is, Hugo - are you prepared to release the AutoCAD files for third party manufacture?
