Try Horizon, HAN 4563; these are the keepers for the 1/4 scale J-3. $9.49 and they come in handy, especially if you drop ONE. At least, then, with a couple used in the jury strut area you can fold the struts down; just lay something between like a soft cloth or bubble wrap so things don't poke thru. Find an old magnet around your shop and you can toss all of your keepers together in your field box and they won't get lost.
