Re: power windows 1969
If I recall correctly, at least on the manual regulators, the appearance is identical but the spring tension is different. Since the 69 window is larger it weighs more and thus requires more spring tension to raise it. The same concept probably applies for power windows, but instead of a stronger spring you have a stronger motor in a 69 unit.
