Looking for suggestions for putting a tach on the padded dash of my '72 Dart. I want it near my line of vision but not obstructing it (especially if I get a 5" Monster) since the car will be mostly street driven.

Where's the best location? Left side? I don't want it on the column because it will partially block my gauges (which are mounted on a plate replacing the original cluster).

Also I can't mount towards the front of the dash because the foam padding on the front edge doesn't seem to have any metal inside it. I'm thinking of securing a flat plate to the visible metal frame extending back toward the driver, and fastening the tach to that. Any other thoughts?

thanks
Charles
