Called Brasseur Electric Trains today and spoke with Brian(sp?) in parts.
He does have a few in stock! I bought 3 which unfortunately was his supply.
I told him about "The Spring Store" (www.thespringstore.com) where you can enter at least one dimension and find springs. They claim to have thousands in stock. He is going to look and see if they have more. They are $1.00 a piece.
