What about moving the radio to the lower spot? That does 2 things: 1) you eyes have to wander less to find your gauges, and 2) it moves the radio a touch lower so at night the bright flashing lights aren't as in your face. I've already moved my setup in prep for a triple gauge DIN... (attached is link to another thread with a pic of my interior (but no gauges))

Dstickney: EGT? My 3 will be Boost/vacuum, EGT, and Oil Press. I'm also planning to "cut" out the ashtray and put volt & amperage down there...
