What are they worth?
I bought the super six setup we put on my gddaughters volare for $80 at MATS a couple years ago, came with air cleaner, intake, exhaust, carb, was only missing the kickdown and the linkage that went to it. Which I had an extra kickdown I bent to match the correct route, and fabbed the linkage outta stainless.
I've seen them sell as complet sets for upwards of 150-300, so I had a lucky score.
