"This guy" is me, sorry that you're not impressed.
The plastic brace between ashtray and radio din is actually crucial to the structural integrity and it can be fragile. Break it or remove and that part of the dash blows apart.
Shallow double-din touchscreens are very hard to find, especially if you are looking for certain features - Apple Carplay and Android Auto compatibility were a must for me. Particularly years ago when I first did this mod.
I do have a shallow Alpine that has all the features now but my original head unit was a full-sized Kenwood.
A shallow unit MAY fit higher in the hole, depending on it's depth), but they are several components in the way that can not be moved. Also the switches (sunroof, defrost, etc) are mounted at an angle and dip down in the way a bit.
How the HVAC unit mounts will have to be customized too.
The wood has to be cut to fit no matter what you do. This wood is hard to find and can be incredibly expensive. I bought some Zebrano wood and attempted to match the stain and look, don't bother - I spent a solid month without satisfactory results.
Honestly, I wouldn't recommend it. Obviously you guys are impressed and even though I like it the modding that I had to do just isn't worth it because it's not reversible and if you mess something up you've pretty much ruined the interior of your car. Then again, maybe your cars aren't cherry or you just don't care. Good luck.
