Where’d you put an A/M tach on an early A-body?

The ‘65 Dart GoGo I had my senior year in high school (66-67) had a small 120 degree RAC tach mounted on the dash just to right of the left A-pillar. It worked great, and was in the line of sight when you were driving. The tach was in the car when I bought it. The installation was very neat and looked factory, although I’m sure it was probably dealer installed. I found a similar tach on ebay and I’m going to mount it in the same place on the 65 GoGo I’m restoring.
