I had to get some from Inland RV. I think he charged me almost 20 bucks a piece for them!! Ouch! The ones I got from him were close but not exact, I had to shuffle them around to get them in the right locations, his are universal, the original ones are lefts and rights. You need them for the roof vents to angle into the wind when partially open under tow. I guess I could have looked around and found them locally but didn't feel like chasing them down, hence the price I paid. Maybe check with a good Airstream dealer like Ace Fogdale and see what they say, might just send you to Inland,
