Sendte dem mail ang diffen og fikk dette svaret... Noen som kan bekrefte at den passer?? There is only one question that remains before I can say "yes, you can use the Eaton LSD in your axle". The Cosworth 7.5" rear axles use 108mm CV joints, whereas the other 7.5" rear axles use 100mm CV joints. As long as the stub shafts inside the rear axle have the same dimensions (spline diameter, spline count, etc), then you can definitely use this Eaton LSD. Do you happen to know if the Gripper plated LSDs are used in both the 108mm Cosworth axles and the 100mm "XR" axles? If the same unit is used for both axles, then you can use the same Eaton LSD for both axles. I have a feeling this Eaton LSD will work with the Cossies and regular "XR" rear axles, but it just hasn't been proven yet. Grayson www.mc2racing.com
