So does anyone have a set of calipers that can measure the size hole on the firewall for the headlight vacuum hose grommet?? some people are saying its not exactly 1 1/2 on the dot.... Its a little off.  anyone know??? 1.487?? 1.496??? 1.523??? thanks r

Mine appears to be 1.5 inches. Maybe as a second check measure the grommet that goes thru the firewall???
