That is the part number for a 69 Z28. But not rare. That term is over used. I am sure the seller thinks that because it is from a special model it is rare. They made 20,302 1969 Z28's. The first two years 1967 and 1968 combined they made 7,801. There are so many of those intakes for sale that if patient you can buy one for $300 to $350 in good condition. Price is in the ball park if you really need one.
