			Just got done with this same project.  You are correct about not being able to get a torque wrench in there! 
 
Inner bolt and nut need to be tightened with the car on the ground.  If you can't do it that way, at least get a jack under the hub and lift the hub up to put a load on the assembly. 
 
Like you, I ended up torquing the inner bolt and nut as tight as I possibly could.
