727 yoke wont come out. What's the trick ?

Got it off with a little hyd. pressure. now i just have more questions! ever seen this ? the other shaft is from a BB parts trans. same splines. looks like this one was cut off or ground for some reason. maybe it shattered a joint/yoke in the past and someone cleaned it up ? anyone seen this or done this ? Motorhome special ? is this shaft serviceable ? or use one of the others i have. got 2 more, one from a BB and one from a SB. they the same? the 440 based 512 should be somewhere just above 600hp. says Hughes. this yoke has 5 1/2" of splines in it. looks to be in good shape. no damage. Drivelines NW said they include a new yoke with the new drive shafts. No cheapy parts.
