OK, just trying to finish up a front-end on a 66 GMC.
I couldn't find anything in the GMC manual on tie-rod ends. I ended up with 40 ft.lbs, but that was a guess. The manual does not bother with torque settings for all fasteners, seems to be hit or miss. In the specfications they list out sized and dimensions as if you might just mill your own stuff. :-)
