I started off with a dashboard from a WRX I got off ebay and built everything around that. After cutting the dashboard to size I built a fixed shelf for it, a custom center console to house some buttons, shifter & handbrake. Finally I put it all together, carefully hiding all of the cables and below are the results.....
I can give more info if anyone has a question and if you are interested in seeing a video I just started a Youtube channel where I've got some vids of it in action and I plan to put some more of mods & builds I do in the future.....
