I was thinking that someone with some free time and a 3d printer should design a new center bezel that relocates the vents vertically on the sides and leaves the center panel open to mount a double DIN more easily.. Would just have to figure out the ducting behind the dash..
It's not a hard mod to install a "double din" into a 90's van.
To "re-design" would be a full time job for a few months. NOT that it can't be done, but it would almost be the design of a new dash.
I now have something to look forward to when I finally get to retire in 80 years. I got a call from social security yesterday and they said they have me scheduled to work until noon on the day of my death!!! I was kind of excited, I get at least an hour off!!!
