Hi Chris,
The stabilizer is a 1/2" x 1 1/2 inch little metal box that's screwed to
the firewall on the dashboard side. It's up above your clutch knee. I've
replaced two of them trying to get instruments to work "right," with no
change in the instruments' readings, so am attracted to Bob Allen's
ideas.
