$3.60 with free shipping @ FRONTX - Webstore - Panel Mount Internal Cables (details @ FRONTX - Panel Mount Stereo Audio - 1/8 (3.5) Female - bulkhead stereo audio female to header/pinout).

I am going to also get 2 repair wires 000 979 009 and solder the pins onto the three wires after I clip off the 1x3 connector on the cable above. I am planning to install the jack in the right-most dummy button above the stereo. At least then, I'll be drilling a hole in a replaceable part. I'll then be able to plug a 3.5mm male-to-male from my mp3 player into it and unplug it and throw it in the glove compartment or center armrest when I don't want it visible.

So, $3.60 for the cable and $8 for repair wires sets me back $11.60 for making it myself.
