There's a guy in Flordia that advertises in the little ads in the back of car mags. He makes an adapter piece that goes between the end of your speedo cable and the tranny. All you give him is what your car is traveling at (MPH) ) and what your speedo is reading. He does the rest. Ir's a small gear reduction unit I think. Mine is off by .02 MPH (measured on a 100 mile Interstate trip). Close enough for me.
