I have been contacted by quite a few people (here and on Cuda-Challenger) expressing interest in these new nylon pieces. I will be placing an order soon to have a bunch made after I've figured out how many. In the meantime, I will be getting back to all of you soon with responses to your messages. Thank you for your interest.

BTW - Here are a few photos showing the new nylon catches attached with pop rivets to the spring steel legs. I ended up having to slightly hone out the holes in the new pieces in order to get the 1/8" rivets through. They didn't need much; just held a 1/8" drill bit in hand, and pushed it through while twisting, and then back and forth a few times.
