Some of the info isn't quite right for 81. Page 9 shows the dash with the correct wiper and headlight markings but there is no "Check Engine" light.
I love stuff like that. I've got one of those for 1980, also purchased off of Ebay. I've also got a 1980 Z28 showroom poster that looks like it was taken down off the dealer's wall and packed away for 36 years.
For you people with an 81Z28, this video appears to be from the GM promotion film. http://stegmiller.midcoip.net/~gary/81z282.avi
