I just purchased a '96 Cobra and it had some crappy aftermarket gauges in the instrument panel. A buddy of mine gave me his stock panel so I decided to change the gauge faces back to stock. Well, I took it apart, took the aftermarket faces off, then put on the factory faces and now everything is Fuuuuuuu. The RPM needle doesn't move and every other needle is active but waaaaaay past it's normal parameters. HELP!!!!!! The car runs but nothing on the panel is doing what it should!!! Did I just seriously F up???
