Wasn't it a late availability option for 70 therefore making it pretty rare for 70 cars? At least that is what I have always believed to be the case.
I think it was a mid to late year addition just before cross over to new model, and it is seldom found on a 70, like you said, it is pretty scarce
...... hard to find color, i personally like it over the Lime Light, but i would have a car with either FJ5 or FJ6.... this is just my personal preferance of course.
