A/C line routing

I have a '74 Dart Sport 318 which came with factory A/C. When I bought it 13 years ago the A/C parts were in the trunk. I recently cleaned some of the parts up, and the others that needed replacing I could get from the local parts store. Since the lines weren't on the car when I bought it, I don't really know where they go. I was on another site and someone posted pics for a '70 Duster for me. They are similar, but not exactly. I layed everything on the floor the way it would go on the car. On the Duster and some other cars I've seen, there is a steel line that runs the length of the passenger inner fender. I know I don't have that steel line, but after I layed the parts out I found I have a line that is steel with a male fitting, goes to a rubber hose, then to a steel line again for like an inch or so, then back to rubber, then steel again with another male fitting. I believe this is the line that runs the length of the inner fender from the expansion valve to the drier. I was wondering if anyone has some pics or diagrams (or know where I can get some) of the A/C system? I found a Dart in the junkyard with A/C, but the next time I went to get some parts and take some pics, the car was gone. I checked the gallery here for the members cars with no luck. Any help will be greatly appreciated. Thanks
