If a plant uses multiple VIN sequences (like one set for Chevy and one set for GMC) they would increment up independent from one another. For a Chevrolet truck built in Fremont for the 1971 model year the VIN started at 100001.
No - it's assigned long before that; Prior to when the build sheet(s) are broadcast to the shop floor. The body build starts days before the frame line, so it is going to appear on the cab well before it is stamped on the frame rail.
Maybe. That's a pretty small number for a truck that was built in May of 1971.
At an absolute minimum Fremont would have easily built 120,000 trucks between September of 1970 and May of 1971, assuming 45 jobs/hour and 2 shifts production. At 100 jobs/hour, 3 shifts and some overtime you are at 400,000 built. If I am reading your VIN right it is 1Z6xxxxx, which would indicate around 500,000 trucks built.
I wouldn't be surprised if it was 224,419 or 324,419 or even more likely 524,219 (even if only the 24419 digits appear on the sheet). In any case you might look around and see if you see "19" or "419" marked on any of the components.

Real interesting, and thank you for that great information.
Yeah, that 24419 must be missing a digit. I thought something was up when I posted that, it doesn't make sense. You're right about my serial number starting with 6, and you're probably correct, the "5" in 24,429 is missing.
If I understand it right, the serial numbers start over when new models are produced (eg, with 1972 models built during 71-72).......................So, if I get the meaning, mine was 500K-ish Chevy truck built at the Fremont plant, for the 71 model year. More like the 555K-ish truck rounding to the nearest thousand, without giving up the serial number
