I've gone & done it now

A year ago last weekend I installed my new stereo. A year ago next weekend I dropped off my car at the body shop. I didn't have time to hook the heater cables back up. At this point, I only have one of the little clips/clamps that hold the cable sheathings in place. I've looked everywhere.:disappoin

I can't remember the exact way to hook them back up either. Most look self explanatory. A pic or two would help a lot. I've been trying to hook up the longest one with the one clip I had put somewhat back in place. But it is hard to move the vent/heater lever all the way left. I've looked at it more closely. There are slots, and screw holes in two places/ positions. Should the cable go on the short stub on the bottom, or the long one on top?

This is a '73. has anyone got a pic or two of how the cable ends are actually routed? Does anyone have any of the clips/clamps that hold them in place? Any suggestions are much appreciated.

By the way, when I was searching this topic, Escanlons long explanation of what the cables do was very helpful.
