I dropped by Autozone yesterday and looked on the tool rack. There is a smallish torque wrench on the shelf and a much larger one. Both are in the $20-25 range, but I did not see the quarter inch beam unit I mentioned.
Factory manuals, at least American ones, are usually very complete. The Chiltons and suchlike can be very misleading at time. Some of the things I read in the Toyota manual reinforce my previous statement. Dont know whether it is a language translation problem, or a more basic language problem;>)
