BTW, on the re-use of the bolts..... I suspect a lot of failures in the past could be traced to inadvertent overtorquing. I bet there are a ton of guys who are sloppy in their work, and who don't clean and dry the threads on rod bolts before torquing them. It's pretty critical on SBM rod bolts, because the book torque of 45 ft lbs is right up near the limit of the bolt torque IF the threads are dry. If they are oily and you put 45 ft lbs on them, they are going to be well past the max load of the bolts and into the yield region.
