Hoosier Hurricane (2/20/2024)
T-Bird tachs are mechanical tachs and would require a tach drive distributor. Maybe you need an older Sun or Stewart Warner electric tach to be period correct for your truck.
Hoosier - You are correct. Been shopping around for a couple of years weighing those exact options. Do like the SUN & SW tachs but difficult to find a reasonably priced working example and not interested in the more common 8k dial scales.
I have a source that can convert cable-driven to work with a conventional coil signal. Trying to keep things looking 'somewhat' period-correct. Without going big $$$. If a 57 bird tach ends up not working/looking decent in my truck, it could always go in the clock spot on the 56 crown.
