Myself........I'm in the process of also doing a "redesign"..Plans so far.....
Center the speedo & tach on the steering column
Move the location of the amp/oil/water/fuel gauges to where I want them
Relocate & update the rocker switches
Add some additional controls, ie. electric E-brake, 12V & USB outlets, embedded iPad (GPS, WiFi, Start/Stop engine, HVAC controls, Bluetooth, Telephone, radio, etc.)
Delete ashtray
Glovebox for storage of paperwork, do-dads, trinkets, and what-nots...probably add a door.
Love to put a very thin, narrow small non-evasive overhead console to house interior lighting, radar/laser, garage door opener, etc.....So far haven't found a suitable transplant......may have to fabricate or just say the hell with it and integrate the controls into the iPad and blah blah blah....
Still have to decide what finish....leaning towards wood, because I want the insets on the door panels, as wheel as the steering wheel to all be of the same finish.......but then again maybe leather. And now I am introducing a full roll cage so that the car will very capable of being a track car....that adds another "structure to deal with integrating as "non-invasive" as I can come up with.
But yeah the dash is the center piece I feel of the interior........I've got a lot on my plate to try an bring the car into the 21st century, yet also try to keep the 60's-70's cool.......I don't even no if I have the vision/imagination to make it work........time and $$$$ will tell.......
