This is interesting.Yes-- The early ones did have a crimped hose on the top condensor connector. Remove the core and take it to an ac shop. They can use a crimper to put a new hose on it. The hole on the core side of the crimp ferrel most generally must be ground somewhat to fit over the connector on the core.
My '76 definitely has 3 rubber hoses, which are detachable from the car (I've already removed them), and have threaded fittings:
1. Compressor Manifold to Condenser
2. Compressor Manifold to Evaporator
3. Expansion Valve to Drier
The drier is fitted to the condenser on a direct hard line. I don't see any rubber lines crimped (or otherwise permanently attached) to the condensor.
The compressor manifold is all one piece in steel (I see that on some later cars it appears to be constructed in two parts, joined by rubber hoses). I've attached a photo (not mine - it was posted to ebay, but is identical to what is on my car. That was listed as a 73-76 Compressor Manifold.
This all looks like factory, though perhaps someone did a good job replacing the original condenser at some point?
I've just sent my hoses off to be rebuilt/replacememts made - added photos of them as they came out of the car. If anyone needs close ups of the end fittings, I have them.
