1970 Factory Rally tach

I'm pretty sure , when I had one, The needle swung ClockWise from bottom left ,up over the top, and down to bottom right. so zero wouldda been at 8 o'clock

Mine was too slow, mounted too low, and too hard to change focus on from the road; so I bought an after-market tach, mounted it on a sliding bracket atop the dash, and swapped a vacuum gauge into the tach-hole.
