I came across some SRAM stuff. 9.0 ESP grip shifters and a 9.0 derailleur. Not sure of age 3-5 years old? So anyhow this may be another option for me. If you have stuff like this for sale let me know.
Also am missing a piece on the derailleur. Have not see what is missing but it goes between hanger and derailluer, a spacer of some type that keeps it from spinning around when bolted on.
Thanks,
