I have a pair of t-rex springs in pro-jump frames you can buy, they need new feet on but other than that there in good condition. I don't need them since i have a pair of pro energys and i have no use for 2 pairs of stilts as i don't have time to use them.
If your interested pm me and i'll see what i can do about taking pictures, if not then good luck buying a new pair, i read about the contract issues and it seems to be difficult getting a new pair of 7's atm :/
