And his replacement dash was from a compatible year, not a 2004+. The 04's not only have a different cluster, they have a completely revamped, rewired and rerouted harness throughout the whole truck. And a new Smart Junction Box to replace the GEM, CSM and fuse panel. Even if you had a donor vehicle and all of the documentation, swapping in an 04+ dash into a 03-back would be a nightmare.
