success!
I secured a pair of rods via a phone call to an online parts guy yesterday. Their quoted price online was $145, but after I spoke with him, he learned from his manager that they had just received two pair from VWoA, to be sold at a deeply discounted price, and so I got one of those two, for $65 plus tax and shipping.
Apparently VWoA has 700 pair of these rails in stock, and they want to move them out of inventory. He confirmed that two pair were being sent to every dealer in the country, but that it would be up to the individual dealer whether to pass the reduced price on to the public. Many might choose not to; that was my experience, in my calls to the parts departments at the closest two VW dealers to me.
I 'd suggest that you call around until you find a dealer who will work with you. Make sure the clerk consults his parts manager, because many clerks are not up to speed with this deal!
