A 1974 Duster - My 2nd one, 41 years later!
might want to re-think the mount position.
if you want to set your idle....or know your rpm @ 65 mph....its OK. but imagine you are WFO ....power shiftin gears while staying in your lane /or on the road.....AND trying to glance at the tach on the other side of the radio.
just a thought.
