I am looking at a 7028264 carb to purchase and would like to get the correct two-letter plant code for the carb which was stamped on the same line as the 7028264. The 6 on this carb looks like it may have been restamped so this would help me feel better about it. If you have the original 7028264 carb on your 68 400 automatic, please pm this code to me or e-mail to mstaley2@triad.rr.com
