Original 1969-1971 Corvette Inner Heater Box Assembly, for Vettes equipped with factory air conditioning. Fiberglass box is in great shape, with no cracks, damage, breaks, or repairs. Heater core is still in place. Some part numbers that I can see are, #3018887 KF2, on a rubber coated door; #3015227 KISIEL, on an aluminum vent/duct; and #3015215, on an outer gray metal piece. Correct for 1969, 1970 and 1971 Corvette coupe or convertible, with the 350, 427, or 454 engine. This particular heater box came out of a 1969 Corvette convertible with a small-block and manual transmission. Dimensions are 17" wide, by 12-1/4" tall, by 11" deep. Unit weighs 12 lbs. Very nice condition! $175. Will ship!
