Confirm torq. specs.

There is a box end to 3/8 square adapter that works well as long as the wrench is perpendicular to the torque wrench. I did my Stealth in the car after a leak and just did my headers with it too.

You can buy 12 point box end to 3/8 square torque adapters but they cost more and you don't get the flexibility of using a open end or wrench length.

Mine is like this.
