Its definatly not near impossible, ive done one for a normal vs dash not a stato, but its probably easier to do in a stato as the side panels sit proud of the factory stez. Basically you have to make a new panel for the climate and double din hole. Easier to do on a stato as the climate control which does not have a mechanical rod is easier to move out slightly to sit inline with the new stereo. If i had to make one for a customer i would probably charge around 300 to make a painted fascia
