Question about Fisher Body date

[Boston14]

My Fisher Body tag is dated 11D. Looking at a 1968 calendar, November 1, 1968 was a friday. Would that be considered as week 11A? Making 11D the 18th through the 22nd? or is 11D the next week, November 25th trough the 29th? Any help would be appreciated. I am tring to put together a chronological assembly of my car based in all of the casting and production dates of the parts. I am lucky enough to have all the original parts except the starter. Thank you.

11D is the 4th week of November.

[Boston14]

Yes I know that, but is it the 18th through the 22nd or the 25th through the 29th?

[Indy 69]

Ah yes, i did not thoroughly read your question, my error.
Someone here will know the days of each week for that month, cheers. 

[KurtS]

Yes.

It's however Fisher decided to handle that month.....
There wasn't a set procedure.

[Boston14]

ok.........., then let's go about this another way ................ Does anybody have or have they seen an 11E car?? I would appreciate it if you guys with access to the database could let me know. Thanks.

I know this does not answer your question, but it may help you make some sense out of it all.
I have a 68 Camaro that is dated 05E, May 1st was a Wednesday. Cheers

OK, lets say the last day of any month ended on a Wednesday, the build date of a car built that week through Wednesday would be MMd or e (depending on the number of weeks in that month, partial or whole). The cars built the next day(Thursday, 1st of new month) would be MMa. So in answer to your question 11A would be just for the one day(November 1st) and 11D would be the 18th - 22nd. IMO

If you look long enough and hard enough at tags it looks like build weeks almost always always changed from one letter to the next on a Monday but the months did not always change on the first calendar day of the month.  If the last day of a calendar month was a Tuesday and that was an XXD week, all cars built on the 1,2,3 of the next month were also XXD built cars, then the build week code rolled over to XXA the following Monday the 6th.  Of course nothing is laid out in concrete and Fisher sometimes forgot to change the build week codes for 2 or more weeks 06A of the 69 model year is a classic example.

If this helps,I have an 11d car. VIN comes up 189 cars AFTER November's end of the month VIN. I asked a local Corvette restoration shop about this very question. They told me that 11d was the last week. That the 1st & 2nd were the last week of Oct. I then wondered if Corvette was labeled in the same guide lines. Sorry for the late reply, I don't get on here very often.

I then wondered if Corvette was labeled in the same guide lines.

Nope, 1964-82 Corvette trim tags were stamped with the DAY the body was built; only the '63 Corvette tag was stamped with the WEEK, and the Corvette format was different (Fisher Body wasn't involved with the Corvette).

Like Kurt said, the month and week codes were however Fisher wanted to handle it. 

You also have to remember that 11D is when they STARTED the body build. Now we can somewhat assume that means the 4th FULL week of November, we are talking about November 24 to 30 of 1968. But truth be known - nobody can exactly define what dates are associated with a week letter.

Check this out. Scroll down to the section on Body Assembly Date. This is from my buddy's Chevelle site, but information should be similar for Camaros.

Hmmmm...the wording in the second section under "Body Assembly Date" looks familiar....  :-)

No one has touched on when the date code was assigned. Seems like all the discussions before stated the date code assigned when the order was entered to start the building process. It really has nothing to do with the week the car was assembled, right?

[Boston14]

My car's VIN is 124679N552528.  According to production figures at Norwood, it was the 666th car built in December. How many cars a day were being produced at that time? Would this number put the car out around December 4th? If that is close, then I would guess that the 11D on my Fisher Body tag was from the week of Nov 25 to Nov 30. Am I thinking correctly? I appreciate all the input!!
