I am the DO.
I don't like those clips at all (nothing personal!). Seeker, who's doing an amazing build of his RS armour got his clips from Quixotic5894. I'm not sure if he is making more of the clips, but it might be worth sending him a PM. Otherwise, TM is selling some very nice TD's that are finished and ready to go, and also sells some clips or aluminium bars you can bend yourself. Keep in mind that the TD supplied with many kits use a tube diameter that's too small, and that the original one is larger, and if you buy finished clips they might be made for the larger kind of tube, requiring some adjustments on your part.
