Removed a couple of those. The a/c pipes are easy to get out if the engine isn't in the car.
(But yep - nightmare otherwise!)
The coolant pipes on the heater matrix though...
That condensor is shagged. No surprise - the corrosion on the fins causes them to burst. Don't notice it on the car because it gets trapped between the slam panel and lower cross member, but when they come out... Boom!
