When I crawl into the area behind the seats with a light I can read the date 5/18/68 and the paint code 929, written in chalk on the underside of the rear deck on the raw (unpainted) glass of my 1968 coupe.. Can anyone tell me if this means the car is an early, mid or late year production 68? When looking through parts catalogs or reference material is read plenty of reference to part applications for early 68’s and I would like to know what differentiates and early year to the later year production run. Thanks.

That could be the estimated production date pulled from the build sheet and scribbled onto the body panel way before the trim tag was installed. In a way, this was the "post its" form of communicating with other factory workers during the St Louis assembly plant days. Its possible because it was a new body style, they were tracking how long it took to get through the factory assembly process. Can you get a photo of the script?

Adam's right on...the trim tag (official build date...sort of) was attached at the conclusion of body assembly and the final paint booth and polishing and just before the trim assembly began. Marriage to the chassis was at least another day or two away and rarely does one find documentation as to the day it rolled off the factory floor. The trim tag date is the constant here and most referenced date but you must understand the context in which it stands.

Changes were constant throughout the 68 model year and any reference to early or late is simply an approximation. Your best source for documenting what occurred when is the NCRS 68-69 technical reference guide. It details most of the known production changes.

Hope this helps
