I just found this site and I wonder how accurate it is. Is anybody familiar with it? What's nice about it is that is shows not only the torque values, but the bolt sizes including the ratings which the part catalogue does not. ... again I wonder how accurate. So far the only way I have been able to tell the strength of the bolts is to read the numbers on the originals, but it would be great if this site shows it correctly.
