Ryan : Your pair of pads look like an interesting project. You can do what James Cameron did with Terminator and revive your pads in to something extra ordinary. I can think of filling the gap with thick sheet of rubber and patching it up using an old pair of jeans or something [light colour]. Sew it up nicely using fishing line.
Tape over the seam once you have finished and pat yourself on the back for a job nicely done.
