The build date project

[71CHEVYSHORTBED402]

This is really turning out, thanks for the effort. Still can't zero my 72 Fremont 146xxx down to a single month, but pretty close. Fremont was really pushing them out too, they may have approached 9K a month at the time.

Any chance 71/72 Chevy Fremont trucks were the most plentiful? The results so far seem to imply so, perhaps age just caught up to 67-70.

Without specific dates you can't tell how many were produced per month, but here's where my 72 C20 would fall for Fremont, as a guide.......146xxx would be Feb. or Mar.
