I can only speak to US spec cars that I know about.
The two that I know are mine, and Alfreds (66andblue).
My VIN ends in -7262 and was a January 1969 production. Alfreds is similar vintage; both were located in the same location.
That would be the door jamb, left side (drivers side) mounted underneath the A pillar.
I think some later ones had it on the other side of the door jamb, but not sure. I know the location of mine is correct, and Alfred's as well.
