This is the duct that attaches to the blower assembly inside the top center of the dashboard. Depending on the air-conditioning or heat mode, it either directs air to the defrost duct that sits on top of it or out toward the center and outboard vents. Cleaned and detailed original that may have some minor cosmetic flaws. Vacuum actuator & seals are not included. See part #02-123 for a completed reconditioned original. Shown as #10, #11 & #12 combo in the assembled ducting photo.
