I got to thinking on the way home from the plant that the figure I gave might be a little high for stock mounting bolts. Us racers tend to upgrade the bolts to a Grade 8 bolt or better making sure the threads fully engage the threaded mounting boss in the frame. Lengths change depending upon what else is added on top of the shock (Peter May kit, Carrera add on shock, etc.)I'll use a good lockwasher and a flat washer under the head.
So, I looked it up in a Bentley, a Haynes and a BLMC manual. Bentley and BLMC used a figure of 25-30 lb-ft for the torque for stock bolts. Probably dry too. My version of Haynes didn't have anything listed.
