The electronic speedo compensator is for the 99-up stangs. The 96-98 use a mechanical speedo compensator. All you need for you Cobra is a 23 tooth speedometer gear that'll run you about $15. Or you can get the mechanical speedometer compensator. Sean Hyland sells them for around $130 and Dallas Mustangs has them for about $90. Pick up a Muscle Mustangs and Fast Fords magazine and look thru the ads in it to find you a speedometer gear.
