It was a stand-alone option in 1986 (RPO D88) for $80. It was part of option packages in 1987 and not available separately.

Willie,
You said it was only part of the package in 87? According to the numbers, they produced 901 of these in 87. You told me a few years ago that GM started counting them individually, then decided to count them as part of the package. This caused the counts to be inaccurate and 901 is not a realistic value.
If that's the case, then the last statement you made is in error. Is 901 accurate or were they part of a package only, or ?????
Also, they work by sensing the amount of light infront of the mirror and also behind the mirror. If the amount of light is brighter behing the car than in front, the mirror flips via a small motor inside the mirror. The dial on the mirror allows you to adjust the sensitivity to the amount of light diference infront of and behind the car.
You can test this during the day 2 ways. With the car parked in the sun, put a flashlight to the sensor and the mirror won't change because the difference in light from front to rear is minimal. But, if you park the car in the garage and put a flashlight to the sensor, the mirror will flip.
I had to rebuild mine last year. It wasn't working correctly. I think I had to solder in a new sensor.

Yes, 1SD on Sport Coupe with LT (coupe) and 1SC on Z28 (coupe).

Not exactly. 1987 was the first year options were grouped into packages, supposedly to make it simpler for customers to order. I believe it was a way to sell non-popular options. In any case, I think that GM initially made an attempt to count the indivudual options and gave up because of the difficulty presented by the option packages.
This caused the counts to be inaccurate and 901 is not a realistic value. If that's the case, then the last statement you made is in error. Is 901 accurate or were they part of a package only, or ?????
I can see why you would say this if you interpreted by statement wrong. Take a look at the numbers of any options that were included in the packages only. I believe all these numbers are wrong and my reasoning does make sense. Here are some:
1,385 Power Drivers Seat
6,509 Power Windows
8,413 Power Hatch Release
14,743 Air Conditioning
4,913 Cruise Control
to name only a few. These numbers are extremely low, considering there were a total of 137,760 Camaros built. Compare these numbers with 1986 and 1988 numbers and it becomes glaringly obvious:
2nd column = production figures
3rd column = total Camaros that year
4th column = percentage equipped with this option
Power Drivers Seat
1986 32,045 (192,219) 17%
1987 1,385 (137,760) 1%
1988 16,176 (96,275) 11%
Power Windows
1986 110,155 (192,219) 57%
1987 6,509 (137,760) 5%
1988 60,622 (96,275) 63%
8,413 Power Hatch Release
1986 109,616 (192,219) 57%
1987 8,413 (137,760) 6%
1988 55,852 (96,275) 58%
Air Conditioning
1986 167,602 (192,219) 87%
1987 14,743 (137,760) 11%
1988 88,431 (96,275) 92%
Cruise Control
1986 106,431 (192,219) 55%
1987 4,913 (137,760) 4%
1988 56,692 (96,275) 59%
Now, do you see why I believe what I do? The 1987 figures are wrong! That's for sure. Why? I speculated above. If you can come up with a better explanation, I'm all ears.

Based on the info posted, I see where the discrepancies lie. Chevrolet didn't keep track of how many parts were pulled from the parts bin??? It seems only obvious that keeping an accurate count wouldn't be too hard. I'm sure the accounting and inventory departments needed more accurate counts than are published!! Too bad there isn't a way to get more accurate numbers from GM.
