I nearly peed myself Zack...
Dude, your ideas are awesome indeed. So in honor of that imagination, I have to give you advice. You can go to any electronics shop/ home improvement store and pick up some... Well, for lack of a better term, roach clips, and use them with some regular old wire, maybe even gluing them together to a point... Ifyou use one red and one black wire, you sure can make some realistic jumper cables. Even if the prop versions are cool as heck by themselves, they ARE just a prop...
Sorry to cause such a stir with the cables folks!!! Sheesh, I had no idea they were such sought after pieces... Zack has a point though, they were pretty hard to notice.
