I need to install a new one on my '79, and I see no way to attach the new liquid line to the condenser without removing the radiator core support. The liquid line runs between the core support and the wall of the engine bay. The fitting to connect the liquid line to the condenser is fixed. It appears the entire line will have to be rotated to screw into the condenser, and it seems impossible to do that without removing the condenser and radiator support. So, if you have to remove the radiator core support, the radiator is coming out with it.
The only other thing I can think of is there are two liquid lines for a '79, one for early '79 and one for late '79.
I hope someone tells me I'm wrong, because I've been putting this off due a lack of desire to remove the radiator core support.

So, the new line arrived, and nope, the nut does not turn. I'll check again tomorrow to make sure the new line's nut is not corroded and stuck.
Thanks for the suggestion.

The old line was boogered durring an attempt to disconnect it from the condenser. The source of the said boogering occurred when the nut did not turn. The entire line spun, and kinked due to overzealous torquing.
So, the new line arrived, and nope, the nut does not turn. I'll check again tomorrow to make sure the new line's nut is not corroded and stuck.

The line can be fished through the rad. support and the fender skirt. Just make sure you don't crossthread the fittings.

It was a major pain to do it in the last Pace car I worked on.
Wound up having to remove rt side core support bolts and rt hood hinge. Then gently pry between core support and fenderwell till I could slip the line down between them.
I could not fish it through from below& through grill or from top down.
You're talking about the aluminum line from condensor to switch on the fender, correct?
flex hose from compressor to condensor was no trouble at all

I took my replacement liquid line and factory line to a machinist that is making a bracket for my ZZ4 engine. He looked at the end of the lines that attach to the condenser. The nuts do not turn. The best he could tell there are multiple swages of different diameters on the end of the line that prevent the nuts from turning.

I'd pay double that for a nut that turns, and the ability to avoid removing the core support. I'll give Riks a call. Thanks!
