One of my 67's swb has a vin ending in 102500 (not exact ) how low is this on the low vin scale and what was total production of the 67-72 model shortbeds ?

a) Not terribly low, when compared to 0001...

b) Keep in mind there were several assembly plants producing pickup trucks, each with it's own VIN sequence.

Said differently, there would be several vehicles (with different VIN pre-fixes) ending in 1025xx

Well that would raise it up there now wouldn't it ?

Well - the point is not just the 10 vehicles with the number 102500 specifically (one from each plant), but the preceding 102499 vehicles prior from each plant as well.

So that makes it one of the first (10 x 102499 = ) 1,025,000th vehicles produced for that model year!

Don't the serial numbers start at 100001 which would make it

10x2500= 25,000 ?

1967 production being 43,940 =4390 per assembly plant

and with total short bed fleet production 67-72 being 257,848

I hate math that's why I asked

so it's just a mid number for that Flint factory year

Yeah, I understand that 4 out of 3 people have trouble with math.

Yes - you are probably correct. I messed up the "starting at 100001" part. Got in too big a hurry.

Also - during my day - GMCs started at 500001 and incremented up in their own separate VIN sequence. So they would have been added into the mix too. I think you'll find that was the case with some of the earlier model years as well.

There were different start numbers for the VIN range depending on the year and plant. Concurrent runs for Chevy and GMC or different lines in the same plant using different start numbers. Each sequence was plant specific but included all light duty conventionals built at that plant or line for a given MY. So K5 to C30 plus IIRC Suburbans and Panel trucks used the same sequence for a given plant or year.
Since each plant had varied production of models it is incorrect to say X number were built at a specific plant based on population totals. As I have said before all the published production data I've seen is suspect and rife with typos.


But coming back to the OP's original question, your example would be the 2500th conventional cab, light duty truck truck produced at that plant (or line), that year, intended for sale.

Your "total SWB production 67-72" also begs the question on how do you want to break it out.

After all that covers eight Chevy pickup model numbers per plant per year.
CS10703, CS10734, CE10703, CE10734, KS10703, KS10734, KE10703 and KE10734. Not to mention the GMC models that also included a seperate model number for V-6 trucks as applicable. Nor does it include any swb chassis cabs for either brand that may now be converted to pickups.

I'm sure Bruceman1968 will drop in and tune this up more later.

Every Fremont "Z" 69 SPID I have currently filed is in the 800,000 range. The lowest is 804647 and the engine was unfortunately a NOM/replacement IIRC.

The engine date on you POP will give you a close production date. I know you have it I just can't read it! Engine casting dates from the block, heads and intake cross confirm. Plus we could compare the numbers on the trans and rear axle housing but those are much broader a timeline.
