After some serious sweating in the shed over the last 4-5 weekends (humidity) and much help from all the legends on this site, I managed to get the factory shifter and console in and working. Had to make up a prototype pointer which I'm thinking of 3D printing and selling if there's a market for it.
Looks ok I reckon, better the the Frankenstein Gemini shifter.
Thats again for all the help regarding wiring and heater rebuild.
Cheers
Nando
