It's a 1970 C10 with the world's smallest brakes (fronts are 11 x 2"). The wheel cylinder has the hoop integrated into it, which the anchor bolt goes through and ultimately into the spindle. Hopefully I have painted the picture well enough (due to lack of an ACTUAL picture currently!). What is the torque spec on that anchor bolt?! Anybody know? I have a factory shop manual that tells the inch lbs torque on the smallest most insignificant hardware on the whole truck, but not that bolt! I'd like to get it tight enough, but not snap anything off putting it back together.
Thanks in advance!

This is as close as I could find. Seems pretty high to me but I guess that could be why they are so hard to remove....
Here are some torque specs for a 1969 chevelle out of the GM chassis service manual.
FRONT SUSPENSION
spherical joint upper stud nut 50 ft lbs
lower stud nut 80 ft lbs
stud to control arm nuts (service) 25 ft lbs
steering arm attaching nuts 85 ft lbs
shock absorber upper shaft nut 8 ft lbs
lower attachment 20 ft lbs
stabilizer bar frame bracket bolts 15 ft lbs (remote but could be part of your problem)
link nuts 15 ft lbs
lower control arm inner pivot nuts 80 ft lbs
upper control arm attaching nuts 50 ft lbs
collar bolts 45 ft lbs
brake anchor pin drum brakes 130 ft lbs
brake anchor bolt disc brakes 120 ft lbs

rear bushing 80 ft lbs
lower control arm front bushing 80 ft lbs

Another site mentioned 65# but that doesn't seem like enough....
