What torque for shackle bolts?

Just replaced all 4 shackles on my 69 cj5.
I realize the leaf spring/shackles need to move, but is there a torque setting for shackle bolts?
Just snug them?
Any info appreciated!

 

When I did my stock height Rancho Shackles, they said 15-20 pounds.

 

With a nylock or prevailing torque nut on the end, I was told to tighten them down until you can just turn the bolt with a wrench

 

Appreciate it guys. I've been checking google and finding 3 answers...24lbs., 100lbs., and tighten just enough til you can spin it with a wrench. 100lbs seems WAY too tight to me. That's like a head bolt!

 

FSM sez 21-30 lb-ft. See page 346 S-5e FSM.

 

100 pounds would be so tight that your suspension would probably not move IMO.

 

The spring mounting suspension bolts (all) as stated in the FSM,are torqued at 65-80 so I suspect someone just took that as anything having to do with the springs. That would be my guess.
