All kidding aside, I bet we see an example or two closer to 3-4 weeks off sooner or later.

It was my cars 38th birthday yesterday...and I forgot. Sorry Challenger. You are looking a little better than you did at this time last year though.

Month & a day late on this one, C08 for December 8th, 1972 on the tag (1973 model year) and January 9th, 1973 on the Mylar door sticker;

Another late build, from a 1978 car this time. Note the B07 SPD, but the print time on the broadcast sheets is for the 10th - three days later.

Thanks to Casey for sending this one in.

It sure looks like 11-12-1340

The zeros have a / through them, a few folks mistake them for twos.

Barry I can not remember what happened in the strike years if Chrysler was the company that was the strike target or the second or the third to have there contract signed or not. I believe 1984 was a strike year in Canada. I believe the strike at General Motors was 21 days. I can not remember the other years before this. In Canada the contract before 1985 were all 3 year contracts. This meaning 1981,1978,1975,1972 could be strike years. I know in the USA each local has its strike time. This could be some reasons why the paper work would say: Example Seq. Build date of 10-11 and the vehicle because of a srike would delay the vehicle being built by the strike time to 10-29. This is just one of the reasons the build would be delayed for periods of time.

Any way you cut it the SPD is set in stone by Chrysler.Its stamped on the fender tag.It's on all factory and dealer documentation.It is used by the Parts Department for determining parts procurement....."up to and after" dates.Correct or not it is the date that Chrysler intended to assemble the car.Again correct or not it is your cars birthday.....Chrysler says so.

A cool 1970 example of an AAR that was built a bit early. Compare the SPD date to the month on the Mylar door sticker;

Here is one that was built late. April 27 SPD yet the door sticker says May;

Question for you Barry and Co.
I have a St. Louis built roadrunner convertible with a SPD of 4/16. It does not have its original motor but I am assuming the trans that came with the car is (it is missing its VIN stamp). The information I have been able to come up with which give some clues as to when it was built:

Axle housing assy dated 4/23/69
8 ¾ sure grip assy dated 4/22/69
3:23 ring gear dated 4/19/69
3:23 Pinion gear dated 4/16/69
Trans assy date 2818 4/15/69
SPD of car 4/16/69

I estimate (SWAG) build date of car between Thurs 4/24 and Wed 4/30 1969 What do you think?

Also;
Do you know if this kind of shift in production could have affected whether or not my trans was stamped with its VIN? I am assuming the trans I got with the car is correct and it's assy indicates that is a good possibility. Anyway, here is a picture of the trans. ID pad.

I would say that is the original transmission for your car.It has the right production date window.I have seen other A833's with the VIN # stamped and no other info on the pad.I have a 2817 A833 on my database that was for a 422 SPD as well as a 2819 A833 that was for a 430 SPD.Your RR should have a sequence # in the 9G251xxx to 9G2522xx range.

Thanks for the info. It does indeed fall within that range (251868).

Thinkin out loud here so bare with me...and comments or observations are welcome.....

With the info you have on your database the indication further supports my trans being the correct piece. Not sure how or why the VIN stamp was overlooked on some cars... strange.

I am going to say that my RR was built on 4/26 +/- a day based on your info - it would seem reasonable to conclude that a trans with a 2818 assy date would be earmarked for a vehicle with a SPD between 4/22 and 4/30 - so I put mine squarely in the middle.

The driveline part dates further support this. If my car had been built on its actual SPD of 4/16, the trans would more than likely have had an assy number in the 2808 to 2810 range.

2817 833 with 4/22 SPD from your records

2818 833 with 4/16 SPD My car... possibly data plate stamped wrong and should have been an SPD of 4/26 or was late build and given a trans that was assembled and slated for a later SPD car - more than likely the latter

2819 833 with 4/30 SPD from your records
