This is a tricky job that I would not recommend unless you are pretty confident in fabrication/ cutting.
The plastic centre console looks at first to be the main issue but you will find the the metal bracket suppoting the dash structure is also to narrow to accept a regular size stereo.
The answer? An angle grinder, file, electric drill, craft knife and a ruler!

Using a couple of multi purpose metal straps from the hardware store to re-engineer the mounting points and centre console support. I made it so the lower mounting points use the plastic centre console screws to help streamline the install.
We also now have a nice large storage cavity under the head deck which helps satisfy my quest for space!

Sorry, some of the pics came out a bit blurry. I will see if I can do a bit better!
