I was fortunate enough to come across an old MK Curare kit, but I'm having difficulty finding a set of tri-gear retracts to fit. If you've solved this, please let me know what you used, any mods required, and where you got 'em. I'm open to mechanical or pneumatic, although I think w/ it being an all-wood kit, there's not much room back aft for an air tank. Thanks!
