I have a 60 foot folding boom that has one wing broken off.  It attached to a Flexicoil 2320 cart.  It has deflectors that bolt to a 2x2 bar I believe.  If your interested I could take some pictures and you could make me an offer to remove them and ship to you.  I have no idea what they're worth or what your looking for.  I'm in North Texas it's a long ways away.  There is also some splitters in that system.  I would have to look and see how many.  I think it was a 4 run system.
