Need Torque data on Rear Shocks on 2013 F250 Super Duty 6.7 4x4

[Steve Edwards]

I have a 2013 F-250 Super Duty Diesel 6.7 XLT 4x4. and have changed the front shocks, and now changing the rear ones. Does anyone have a manual that shows the exact torque for the rear top & lower bolts? Also, do you think I may snap off the top stud, in I use an impact gun to break them lose?
