There's a few things that I would like to know about like the "double stripe" S- standard on a Sport Satellite that I have never seen??? The double stripe is not available on any other model but standard on the Sport Satellite? Or is this for '68 models which after looking at it again appears to be as it list a S- standard reflective stripe for the GTX which there was but the reflective stripe on my '69 GTX was E-extra? This must be for '68 B-body models.
