Wheel Cylinder Anchor Bolt

[69GMCLonghorn]

Wow... I had it easy. I just read a thread from the guy that snapped off the anchor bolt while trying to remove it to replace his wheel cylinders. All I had to do was buy an $11 socket and use my impact gun with all it had in it to remove the anchor bolt. So... now for the question:

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!
