I am looking for the rear door window rear track, it is the long piece that goes from the top of the door to the bottom. They rust and the rubber separates from the metal. They are available from the dealer but cost a fortune, cannot find an aftermarket one and any used door I find they are already rusted (I'm from Mass.). I need the whole thing not just the rubber part. Common problem up here.

 

#4?

 

That's the part, where can I get it?
