Topic: Original front bumper date codes

[priceless]

On my 69 Mach 1 is the bumper I bought back years ago. Can't remember the year. Early 80's I'd say. I knew when I bought it, it was an original NOS bumper.

I read Marcus' bumper id in the library section about date codes. My bumper is marked 9 27 1 with a year and manufacture codes of 82 M 69. I know that the date is September 27 first shift at Monroe plant "M". So does the 82 stand for 1982 manufactured in Monroe plant for a 69 Mustang? Why would they even have any reason to date it 9 27 if it was produced in 1982?
Any help appreciated,
Rich

Why date it with month and day? Same reason they dated anything. To be able, if there was an issue at the plant with - for example poor chrome plating on a particular batch, date or time period so they could address the issue.

Ford had these problems from time to time. Just reading sections of the TSB articles and TSIs last night for another members project and Ford sent information to service managers at the dealerships like "for 10 days in march starting on March 12th the wrong bolt were used to attach the lower crank pulley to the harmonic balancer on all ......." and things like that.

Actually, I worded it wrong. I know Ford has to date parts, knew that for years. But, why date a part 13-14 years after the particular car it was manufactured for. I'm thinking because my bumper would still be considered NOS? The reason for the dates/manufacturer stamps?

Let me try it this way. Why would the Ford stamping plan after stamping, after all these years, stop stamping these items. The reason for placing a date on them originally and 20-30 years later would be for the same purpose. Identify what the bumper was made for and when it was stamped. Guess the bottom line is for me - don't need to know why just that they did

Sounds good. So still in 1982, mine is still considered service replacement NOS?
Thanks for any help.

IMHO your is a service part.

The NOS labeling does not seem to have a standard usage/application. Kind of like restored, original, like new, rebuilt ........ terms

If were new it would not be unusual IMHO for a seller to use the term NOS in the ad. A buyer should ask what you mean by NOS in that case.   

In that case you would have NNOS = New - Not so -Old -Stock

The reason for the dates/manufacturer stamps?

Good example: in the 1990's ford parts received a bunch of right side 69/70 hood hinges assembled wrong   ( the part that bolted to the hood was flipped ). After receiving 4 bad hinges and a bunch of phone calls, Ford told the parts manager where I got my parts from the range of dates where the hinges were defective and the bad hinges were pulled from the system. This was when the part itself wasn't dated, but the silver parts label had the mfg. date.  Worked out well cause it wasn't readily apparent it the hinge was assembled correctly or not unless you knew mustangs.)
