X codes started late November/ early December, 1968. D80 was added to the tag in April 69,

[/ QUOTE ] The X code was started the 2nd week of Dec 68. I know this because my L35 camaro was built on the first week of Dec. 68 with no X code on the trim tag. I had to crawl all over the car to make sure it was a true BB car and not just a vin restamped motor, the trans matches as well. Thanks, Mark
