I picked up an LT1 HVAC duct (the part that stretches the width of the dash to all of the vents) from GM Sports Salvage in San Jose for $20. A week later I found out from my brother that I still had the one from my car in the attic (even though I was pretty sure that I had thrown it out). Since this is a pain to ship, I can only sell it via local pickup.

Anyone interested? If not it's going in the trash. I'm flying home in a week and I don't think I can tag this thing as luggage
