I bought a 1968 911L targa a few years ago so I’ve been collecting data from Kardex files and COAs published on the Web to better understand when the numerous changes occurred during the 1968 model year. Here is a synopsis of when the various models were released and when the model year changes occurred. Please let me know if you have additional information to add and I’ll update this list.
