This question continues on above post no where near rite..part of the clue was it is an option wipers are not an option....
also vacuum wipers went away before the 1960s...I had them on my 1950 Ford but sometime in the early 1950s vacuum wipers went away as did the 6 volt system.
SO as a quick reminder here are the clues
It changed formats 3 times in the 1960s in GM vehicles
It was an option....
here is an additional clue this option is found in many turbo regals today....
figured I would tie it into a Turbo question.....
game on
Waiting on GN Rick to take his "stab" at this question......
Maybe the type of wheels could be considered an "option". Steel, magnesium, aluminum. Then there were hubcaps, full wheel covers, knock offs (or whatever the Vette wheel was called that you hit with a lead hammer). Well that's all I got.
I can't believe this question is so difficult the answer I am seeking is very simple. Course the longer it takes the more time I got to develop my next question.
Gotta give an A to GN Rick......faithful even if his answers are not correct......GN Rick I mean this in fun not picking on you!
Keep in mind the 3 methods is in the 1960s the latest design is the same design/format that is an available option in our cars....In other words the last format of the 3 formats is the same as the option in our cars.....
still no correct answer member the clue is this is an option currently in our cars works on the same principle as one of the 3 versions for this option in the 1960s GM cars...
I did not think was question was that difficult. I am signing off for tonite until tomorrow nite keep trying...once the answer is revealed it will be surprising how simple it was.....
Oughta be time for GN Rick to submit his 10th try on this question......
