I want to add 2 more gauges to my truck and was wondering about the steering column vs the over the mirror style. These will be for air bag pressure and aux fuel tank level, so I don't need to look at them on a regular basis. To those who have gauges mounted there which was easiest? Does the column block things too much? I have a stick so I'm not worried about blocking the PRNDL. I already have 3 on the pillar and 3 on the dash. Thanks in advance. David
