That number on the top of the carb the 6-2124 I believe is a casting number. You need to look at the number on the base plate in the rear driver side. It should be a 4 digit number with a letter s /stick or a /auto begining with a 4, 6 or a 9 and end with a letter. 6138SA or 9810S..Check the list that the other guys posted early..
Let us know.....
