Man that is slick. I was looking at camaro clusters on ebay. I saw several that looked like the tach was driven by a VSS connection from the speedo. The connection to the tach looked like it was part of the printed circuit board. Are all of them like that?
My quick peek at ebay looks like 82-89 are the correct years with your choice of 85, 110, or 145 mph speedos. Do you know what the differences are in the different years. I have always hated camaros, so I never paid any attention to them.
