Welcome to the board John. The telling number on your carb are the 992 . They are the manufacture date code for when the carb was built. First 9 is for 1969. Second 9 is for September. The 2 is for the second week of the month. What you have is a late production 69 Z28 carb, but I have had originals with dates that late too. Only problem with that late of a date is you need to find a car with about a month later build date to put it on.
