[DeTomaso] Techno question: brake caliper bolt torque specs

FWIW, Chuck, I don't use the 'lock' tabs either. They are soft steel and 
indent under only mild torque so bolt tension slacks off as the soft steel 
indents. And practically   speaking they are one-use-only as the tabs fatigue 
after one bend/flatten cycle. I much prefer ss safety wire. This stuff should 
be taken seriously- we think a loose caliper bolt may have been the 
proximate cause of Mad Dawg's spectacular fire at that Silver State event.
When adapting Wilwood calipers to a Pantera, the usual way it's done is to 
use the inner bolt in stock position and drill/tap a new hole in the 
steering arm outboard of the second stock one, to match the wider bolt pattern of 
the Wilwoods. No strap-adapter is needed, but on some Panteras the steering 
arm edge is then VERY close to the edge of the new bolt hole and may crack 
under hard braking. The fix I use is to add a filler weld-bead to the outside 
of the forged steel steering arm and dress it flat with a file, to reinforce 
this thin area. It's worked since 1990 for me... Good luck- J Deryke
