Replaced differential yoke - torque for retaining nut?

[suburbanfireman]

Short story - I replaced my differential yoke to a Strange (with 1350 u-joints).  Not sure if this info matters, but I have an 8 3/4 with 10-spline pinion shaft.  What do I torque the pinion-nut that holds the yoke?  I know that shouldn't over do it - isn't there is a "crush-sleeve" inside?  This is new territory for me, so I haven't a clue.  

I read older responses to similar questions.  I tried to find out the "spin" of my differential using an inch-pound torque wrench.  I'm pretty sure things were too sloppy to start with - possibly contributing to my car puking the drive shaft friday?  BTW - The old nut and yoke came off really easy.  I didn't even need the BFH or a breaker bar!

Thanks in advance for any tips / advice.

PS - If you want the long story - please feel free to read my response to Slider's driveline vibration post.

What are the last three digits of the casting number on the drivers side of the pumpkin? 489 has a crush sleeve, 741 and 742 don't.
