Hello all, I have had this idea in my head for a few years now, but have recently gained access to a 3D printer and some design software (along with someone who knows how to use it), so I'm considering trying to to make this a reality..
Basically, the issue is that the dash in my 1985 G20 is designed for a single DIN stereo as is almost every 1980ish and newer facelift dash I have come across. There are some later versions that fit a 1.5 din, but that isn't what I'm after. All of the aftermarket units that I like are full double DIN. I see where a handful of folks have shoe-horned double DIN stereos between the vents and the bottom of the dash pocket. I'm not saying that doesn't work, The radio position doesn't seem to look ideal, and in my mock-ups, the angle/view isn't great.
What I would like to do is design a bezel that would replace the whole plastic section where the radio and vents mount. I would then re-arrange the vents and place them vertically like the vents on the outer ends of the dash, This would leave a space in the center large enough to mount a double DIN stereo in a perfect spot. I could even incorporate in a small visor above the radio spot to reduce glare..
The only issue that I'm running into mentally is the ducting between the new vent position, and the plumbing that is already under the dash. To avoid pulling my dash back out again until necessary. I want to find a dash in the junkyard. Can anyone verify what years are the same as far as the center vent plumbing? I would imagine they are all the same, but I want to verify.
Anyways. Once I have a spare dash to mock this up, I'll update this thread with more details.
Here is roughly what I'm thinking:
