Do you still have the original one from your car? if so there are places that specialize in up-dating them with the modern technology. I sent my factory rallye tach out 4 weeks ago (it did not work anyway) to be updated and it is on it's way back right now. I sent it to Mr.heaterbox in Canada they were recommended by 4spdragtop another member here on the forum and I'm glad I did and the price was right compared to everybody else. If interested P.M. me and I will fill you in on all the details.
