This pretty well echos what I have found. Years ago I bought a ratty '70 Electra for parts. VIN ended 0H101615, and Fisher body tag reflected a date of 08B. Unfortunately I didn't record the body number before scrapping the car. Casting dates on the heads - block - intake were all H8 and H9, or second week in August 1969 matching the body date. This is as early in the production year as I have seen personally. I don't know how many cars rolled off the Flint line per day, but this example was among the first two thousand Flint built cars.
Perhaps for the Freemont plant but as pointed out by another member Flint production was earlier as proven by the 08B production date for a Flint built car in post #6. However verification that the car I posted was a very early car built at Freemont gives credence to the theory that line inexperience likely was responsible for BMD badges being installed on the car's fenders instead of the correct 455 badges as discussed in another thread.
I need to update the general information. There were 70 Buick GSX built as late as the second week of June 1970 "06B" Thanks, Mark
My 70 gs455 has a build date of 06d and a body tag of 0000023 4th week of june 1969 the 23 body tag is cool too pointed lens and other early parts on it too. Hector
Would that be the 4th week of June 1970? I would be surprised to see a 70 model built in June of 69 even though it does have a low body number. Could you post a pic of the cowl tag?
Pointed lenses are the clear plastic covering over the gauges (gas, speedo, etc). Early build cars the lenses were pointed outward. This cause an undesirable glare under certain conditions and they were changed to flat lenses in the December, 1969-January, 1970 time frame. Same as true for clear top radiator overflow lids (changed to black lids) and plastic upper radiator support plate (changed to steel).
Could also show that maybe different plants had different start times or maybe production of big cars started before A bodies. Unless someone has tag showing built week anything is possible.
Cars with low body numbers that had later week build dates may have sat around due to parts delays. Just a guess.
This is one possibility. Also consider that the first few thousand body numbers on Flint built cars were reserved for SCO vehicles. Although this was policy at Flint, I don't know if the GMAD plants had the same policy.
its a fremount car I can text anybody a pic of the cowl tag but i have had issues trying to post pics i just gave up. 626 488 5472 Hector
'A' body VINs at Flint started at 100001 and the body numbers started at 010000 (under 010000 were reserved for SCO cars). The earliest 1970 GS I have registered is under 5000 (VIN 0H10xxxx). The body number is 012288 (as seen on the registry). This car is 08B The latest GS I have registered in 1970 is 06C (VIN 0H34xxxx) with a body # of 293929. There is an SCO in the registry with body# 001957, built in May 1970
I've noticed for 1971, Freemont CA car body numbers started with 000001 and were incremented by 1 for each car built by body style - no SCO. I have no information on the 1970 model year.
nowing the last 6 digits of the VIN may help some, the ranges from Fremont built V8 cars are: 1970: 100001 to 126087 I have the following information on a car from Fremont: 446370z1003xx ST 70-44637 BF 00023 BDY TR 189 B80 58 F PNT 08D 000220 070080 I also have info on this car: 446370Z1006xx ST 70-44637 BF 00033 BDY TR 188 B80 63 B PNT 08D 012915 110073
