So a few months back a kid hit our 2006 envoy denail head on twisting the frame bad.power plant is still strong and running all 4x4 components still good including the lift kit and aftermarket wheels. I had rebuilt the motor and put a built transmission in it with tons of upgrades. My question is can I pull the power plantnharnessnecm and 4x4 system and swap it into a 2003 envoy 4.2 4x4. Hints I have everything needed seeing I still have the completed truck. I just want to make sure my 06 stuff will marry into a 03 chassis. Seeing I can pick up the 03 for 300.00. And it was a very low mile truck 4.2 is locked up. I will be moving all denali parts to the 03 if the swap can be done.
