map sensor bracket

hey whats goin on, i have a 97 ranger (4 cyl) and the map sensor bracket that connects to the header on the passenger side is missing a bolt and that bolt missing is creating one hell of a vibration noise and not to mention an annoying exhaust leak, i don't really know where to find one, i want to get one brand new, i don't want to go to a junk yard, so if anyone has any info, let me know, thanks........
