The impossible air conditioning connection - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So I'm hooking back up all of the AC during reassembly of my restoration, and I've run into something I just can't figure out.

On the line in the picture below there is no tubing nut. I've followed the line up and down and it's just not there. Yet I don't know how it would have ever come off, because the flare is still on the end of the pipe.

In the assembly manual it seems to show the pipe without a tube nut, but that's hardly authoritative.

Could someone with AC (ideally a big block, but probably doesn't matter) check theirs and see how it's connected?

Many thanks for any help! The second photo is just a quick snap of where I'm at. It's still all the original lines and so on (which hopefully do not leak) plus a lot of scuffing, polishing, scotchbrite, and so on.

Is that the line to the dryer? If so look under the dryer and see if it slipped all the way back to the front side of the radiator support when you installed it.

Here it is in my 69 with a 350.

Thanks! Are those new lines? If so, do you know where you got them?

Andy - good thinking, and I did already check that. But last night I woke up in the middle of the night wondering if it got stuck inside the grommet - I'll check when I get there!

They are new. I got them from Classic Industries. See promo code thread for latest 20% off sale. Here is a pic that shows all the lines.

EDIT: Added second pic at a slightly better angle.

A good AC shop should be able to get the hoses made for you. When I ordered the fittings for mine I had the local place make them up. He charged me $25.00 to do it.
