I just started my rebuild today and my friend with a 00 SI rebuilt his motor last week....his clutch has 30k on it(he got CM stage 4) and my gsr clutch has about 88k on it....now my clutch disc looks a slight bit larger(as in circumference, not width), but his is in a lot better shape. I am pretty sure that b series clutches are interchangeable..but I dont wanna make a dumb mistake...hope this question doesnt sound too dumb, but any/all help is appreciated...

 

they might be interchangeable but they are definitely not the same.

 

it's the type of the tranny..hydro or cable...
I am not sure though...
