1G A/C line issue

[Stevens Talon]

I'm working on a 1994 talon DL. I'm having to do some body repairs on the front (was apparently in a bit of an accident, was like that when I got it for a project) and so I had to remove the a/c condenser and on the left side the short medal line from the block on the condenser was stuck and wouldn't pull apart so I had to unhook that line from the rubber line at the threaded joint by the alternator but the threads buggered up.

1st question, is there anywhere to buy the short hard line and can any one tell me what the thread size is?
