Dating of Vitus frames is pretty much covered here: https://on-the-drops.blogspot.com/2016/12/the-peugeot-px-10du-vitus-979.html

The CLB bottom bracket undershell from late July 1980 onwards production models showing the press fit plastic cable guide and the new serial number convention pre-fixed by a letter ("A" starting with 1980) and numerals. In this case, F068314 indicates 1986 (6) August (8) and the number of frame completed that month (314). There are examples of frames with the older style bb and the new serial numbering dating from mid 1980.
