2.8 litre car with Cruise control

[7-up]

Hi,  I have the chance of a UK spec. Audi 80 2.8 coupe. LIke the American spec models, I'd like to get Cruise Control in this.   I can install most things thanks to a 4-year eng. apprenticeship. Please can can anyone send me any advice, e.g.: on parts needed , part numbers of parts, where the parts go and/or anything else !     I guess I'll have to use secondhand parts, which I'm not worried about, as I can also test most things .
