i would call george also. the problem with the ppe stuff is not the cutches or anything because they are all the same but more likely then not the tolerances will not even be close to what you need and without extra clutches and or steels laying around it may be hard to get the right tolerances needed and trust me it wont last long if the tolerances arent right.
i would not agree with you on this topic, i have personally installed 3 of there stage 5 kits and i have very little problem with tolerances, also depends on the tranny builder to know where the tolerances should be for different power applications, dan is great to work with and there tech support is always there when needed!!!!
