follow up from my ac-upgrade thread I have bought "most" of the components for a rear-ac retrofit. and now on to planning to install everything, trouble is I seem to be able to find lots of people 'thinking' about doing it but not much info, maybe photos of wip or diagrams of how to plumb the high/low pressure pipes for the rear evaporator. Anyone who has actually done it could share some details maybe a few photos of how to pass everything? also does the dashboard need to come off?
