Fred,

According to the site I referenced before ( 
http://www.barnbolt.com/trqgdess.htm ) the torque of a 1/2" bolt 
(just a little bigger - 6% than a 12mm) is about 45 ft-lbs. Seems 
like this is close enough. It's not clear to me what the real 
clamping requirement for the A-arm/shock bushing are. When I bought 
my Hall urethanes, a big point was made of the fact that the inner 
stainless shaft was held tight, but the urethane bushing was free to 
rotate - which (the sales pitch) allowed the A-arms to move more 
freely and work better. The amount of force needed to clamp the 
shaft, I would think, is minimal.
