1969 'Cuda scoops

Yes, those are the scoops in the picture of the 1969 'Cuda 440, like I said I am just trying to get an idea for what they are worth, I am planning to put them on eBay in the near future and want to have some reserve I know I will get for them. That is the only formal way I can think of doing this sale.
-thanks far the responses!
