Honestly, I do not like the factory in-dash tach.It is everything but not cool in a 60-70s muscle car at all.That is why I was thinking in something alse. I think the streering wheel mount Sunpro SST802R tachometer will be the way to go.I've seen those in Ford accessory brochures from the period. They were intended as an add-on for Fairlanes, base Mustangs and Cougars, and similar cars that didn't come with a tachometer. They looked cool, but were notoriously hard to read in less than ideal lighting conditions. Adding one to a car that came with a factory in-dash tach seems kinda goofy.
