It seems that every options brochure I see has the (=) style the car Non AC, and I like the(=) better, look on http://thefirstgensite.com/library/69pontiacoptions/69pontiacoptions.swf it shows the (=) style on an custom AC car (on Page 9) and also the whole dash is painted the same color, this also gives alot of info on the options.
There is some great info there. Did you see the ad for the flex fan? Cool! They pretty much say it's the best for cooling without losing HP. They show it with the best radiator too.
