No the spline count was the same but how thick the spline shaft on the clutches was diffrent unless centerforce has partnumber mixed up wich i doubt they do they make diffrent clutchs for ls and gsr so does exedy and competion clutchs call them and ask before you sayanything else plz.......

also i was talking about the smooth part on the trany wouldn't go all the way in to where it was soppost to b/c the clutch pline shaft was to thick it measured to 1 1/4 inches where as the ls zoom clutch measured up to 3/4 of an inch and when we put that clutch on it went on with no problems

i should have called you mike b/c nobody in the south east had a stage 3 6 puck cluth instock
