I like your idea and I might do it as well if I ever get some center beam cars. Have you thought about maybe using some sort of thread to make it look like the cable that holds the load down to the car?
They came out great but you had me afraid that you were going to build the loads from the 2x4s you were cutting. That could have been a long video, lol.
