Agree with Keith S very much on this topic.
When I was in Truck Operations, we had Weight Engineers tracking every part that weighed over 3 pounds. All of the 1 pound and 2 pound things not weighed on a vehicle could easily shift that weight between 50 and 150 pounds heavier.
At some point The Weight Guys (with their computers and "End Of Line" very accurate scales) got an accurate weight for each vehicle produced from that line.
The auto companies had none of that computer capability in the 1960s and 1970s.
About the early 90s is when the EPA and CARB were given actual average test weights for a given model/vehicle.
They then fit those vehicles into given ETW Testing segments for Emissions/F.E. and Performance testing.
I did that Emissions job for 7 years and was Ford's "EPA Rep" for several of those years, making sure that the EPA tested our vehicles properly.
So no surprises on the vehicles weights being all over the place on the 1960s vehicles.
