The build date project

[71CHEVYSHORTBED402]

Reading some suggestions above, especially dates, you might consider a different format. Don't get me wrong, this effort by the two is outstanding, I'm reminded of the effort put into indexing the assembly manual, all we had to do was number 500+ pages

Perhaps this is a usable format. You can sort by any column and I think easier to manager by the task force. Edited:

Date (zero=no day): March 0, 1971
Factory: Fremont71 (the reason for the year is for sorting - I like how you guy's separate factory & year & this will do that. See example below if interested.)
Year: 1971 Perhaps redundant if year is added to factory, but strikes me valuable as a sort option)
Chevy/GMC (gay man's chevy): Chevy, Suburban etc. (See post 119, might be better to add Suburban, Blazers as a note or as another column to sort by, e.g. "Other").
Vin: Zxxxxxx (Not sure you need "Z" but it sorts anyway).
Notes: 71Chevy402 is a bum

Flint70
Flint71
Flint72
Fremont70
Fremont71
Fremont72

On a side, if using Excel for example, the shorter the better. Sometimes it's necessary to put columns between columns to paste right, using symbols. For example:

01/01/1970...Fremont70...1970...Chevy...Z123456...Blank*...71Chevy402 is a bum.

*Blank is a spot for Suburban and that, because blanks will throw off your paste. N/A maybe, but it's not as if you're registering every type.

Edited again, cough). The list of your factories/years and that is a nice placeholder so to speak, but I wouldn't add them to your chart until a truck comes up. Just some suggestions, I'm a bum but long edgeucation in data structure & reports was enough to be happy to leave, with CDO and perhaps PTSD too, them (*&(*)&^ are crazy especially meetings.

I looked at two of the closest dates available with a decent spread: (3-24) Z154193 and (4-28) Z163961. That is either 34 or 36 days (34 if you consider Z154193 was built at the end of the day and Z163961 was built at the beginning of the day). Using those numbers, the average is 287 trucks a day. 287 x 24 (March 1 to Mach 24) = 6888 trucks. Backing up from 3-24, the earliest for March would be Z147305.

Certainly Z146839 was built in either February or March. I'll add an asterisk, ? for the month and a note. Ill bet we can make better estimates soon.

I agree. If a picture was worth a darn I'd take it. The sticker is just too faded. But again, I believe it's a three. If it's March you can bet it was the first week if not day. Heck with it, I took a pic anyway, that looks like a three. A two is shaped differently If true, and I think it is, that's approx. 306 per day and a whopping 9200 a month 72 Chevy Z at the time.

We need a forensic to pipe in, there's got to be a chemical some sort.
