Leafspring bolt torque specs

Looking for the torque specs for the rear leafsprings. I just got the 5.5 11 leafs from Wild Horses. I snapped off two of the shackle bolts in the process of taking them out. Man those were tight/rusty. I need the specs for the ends of the leafsprings/eyelets. It was time to get rid of the crappy lift blocks that the P/O installed and add the 6 degree shims to make my driveshaft a little happier

For the most travel, you don't want to compress the spring hangers so that they restrict movement. I have always tightened them to the point that the bolt won't turn freely.and maybe another 1/8 to 1/4 turn.
