Torque for driveshaft 12 pt. bolts (short)

Thanks Barry for that response. Considering, the location, purpose and high load of these bolts, you never want one to fail. I think I'll elect to err on the side of caution here and shell out the cash to replace them all, thanks.

Thank you Barry for your very reasoned response. As Mr. Spock would say "that is very logical"

The thread will not yield because these bolts are designed this way. The stitching occurs between the end of the thread and the head of the bolt. This part goes above plastic deformation into permanent deformation. If done properly (read correct torque) it may even not show but the bolt is dead.
As this is a precautionary and safety measure, I'm not totally convinced it is really needed. So you may re-use your bolts. But don't whine if something goes wrong...Same for the conrod bolts...
I'm amazed that a lot of people are better that the whole bunch of design people at R&D in Munich added for 50 years of experiment on the roads of the world.
