I would guess maybe a couple hours. A regular analog to analog swap takes less than an hour to take apart and reassemble. You'd need a couple of Torx screwdrivers. It's a T27 for the under dash screws and, IIRC, a T30 for the ones for the cluster. You'll also need to take off the steering column shroud for easy access, but it's possible to get the cluster out w/o taking it off.
