The seats and console swap took almost 3 hours. My truck did not have a plug for the full console harness, so it is unplugged for now. I bought the interior set from a local junkyard. Set was both front chairs, rear bench seats, full console, and 4 door panels. Door panels swap is pending. The driver seat is now power adjustable. Surprisingly was plug n play, no additional wiring needed.

Only issues were a gap between full console and dash, rear doors need a longer lock wire rod and additional mount hole, and no power to USB connections in full console. The trim panel for gap is part# 84127263. The 2500 lock wire rod needs to be lengthened by 3 inches to work with 1500 rear door panels. The 2500 rear door top trim will require a small mount hole to accept a push mount tab on 1500 door panel.
