Speedometer calibration.

Have an '88 Tbird sport with AOD trans.  I am building an 8.8 axle with 4.10s.  I have a 23 tooth gear on the electronic speedo sensor that gives me the correct MPH for my 3.73s.  Anyone ever heard of a box I can put on my speedo sensor to recal the speedo, and where can I get one?
