I had a quick look at the part numbers for this item: Mercedes pn 8370306517, Nato Stock number 2815-12-158-7451, and here is the shocker: the price for each is $1,007.50. They will definitely be wanting to find that surplus somewhere.
I knew I had seen a complete pack on the net somewhere and for whatever reason the grey cells clicked and it is Toronto Scientific. They have a complete rebuilt pack, although the price is "contact for price.
