here is my question... how tight do i need to make this. too loose the it seems like it wont hook up and tight seems like it doesnt wanna spin very easy. granted that its not installed and while conected to the rest of the tranny it might be much easier i dont want to have to take it apart at the track tomorrow (i really wanna be top notch for my heats!)

any replies would be awsome guys... ty
