I've had the speedo/gauges cluster out of my 1st gen Tundra...nothing hard there. Been into the stereo console in the 2015 Subaru Forester...also pretty easy. Been deeper into the whole dash and all associated components than most smart folks would want to go with my 2000 Jaguar XKR.
It is not for the faint of heart, and for me anyway, research before starting is vital. Online fora, and youtube vids are a boon.
