Was browsing online and saw Sun had started making the original Super Tach and the one before that. I thought how cool would that be in my project road runner. I see pics online and the face says Sun Super Tach, but none available.. Summit and Jegs have the Bosch Retroline that is identical but doesn't say Sun Super Tach, just RPM X 1000. What gives? Did Bosch buy out Sun and it's a licensing thing or what? The P/N for the unobtainable one is SST802R. Thanks!
