What is the torque spec for u-bolt nuts holding axle tubes to frame on 66?

[Metalaroundstone]

I have searched hi and low in my repair manuals as well as online and I can't find the torque spec for tightening the u-bolt nuts that hold the rear axle to the frame of my 66 c10. Does anybody know what this should be or where I could find this spec?


Also, is there any particular sequence to tightening these nuts? Is there anything else this is important to know in reattaching the axle tubes to the frame?

Thanks
