I made all the a/c lines when I put air in the Torana.. I bought hardlines in a few various lengths and was able to make/bend them and use them at the lengths they were at and made all the rubber lines to suit too. (bought a crimper, fittings and hose) worked out really well.
With the hard lines, I just measured and planned out a bunch ahead of time to be able to use off the shelf lengths basically.

Can't remember off hand where I got the universal hard lines from...might have been classic auto air, or another place would have to look back through and see if I still have the various catalogs around.
