Rearend Rebuild, Need Help

I appreciate the response but it doesn't reach the crush sleeve to crush it. O.K. I put the pinion into the case through the pinion/yoke hole then when I try to put the pinion through the yoke, it only goes in maybe about a quarter of an inch to a half an inch then I cant get the pinion any further into the yoke. There is barely enough room to put the pinion/yoke nut on without the washer. I still need like an inch left to even reach the crush sleeve. isn't the yoke just supposed to slip onto the pinion easily?

Is it a 10 spline or a 29 spline ? I've seen some 29 splines go on real hard.
