uhm how much splines are supposed to show when installed ?

[Fast68Chevy]

those of you with 4 speed 2wd truck, how much spline is showing at the splines end of the front prop shaft where the rear prop shaft slips on, back from the backside of the bearing and back to the front nose of the rear prop shaft ?
