72 Dart: How many hours to remove speedo

Loosen the column to firewall bolts, remove the column to dash bolts, remove the speedo cable connector on the back of the speedo, remove the screws to the IP, remove the nuts for the alternator guage, remove the wiring to the pins being very careful not to bend or break a pin, hold the column down and tilt the IP down from the top and remove being VERY careful with the pins, 30-45 minutes. 5 hours is insane!
