    The best thing to do is to take it apart then measure what is in there, especially if your parts store says there could be 2 sizes used in your application .

    It could be an 11" or a 12".11" was normally used for light duty and I6 applications.You should be fine with a 12" unit.I do believe they interchange,as long as you have the matching pressure plate.They all should have a 1 1/8" 10 spline input shaft hub.

    Whatever clutch you get,go with a new complete unit,with new clutch disc,pressure plate and release bearing.Stay away from rebuilt stuff.
