took on this 1st gen Expedition project to kill 2 birds with one stone. I have two expeditions one is a 2000 Eddie Bauer with a clean running engine 107k miles on it and runs smooth. This Expedition was hit on the passenger side and bent in the front passenger door frame and some of the backdoor. But the chassis/frame was not touched or damaged just the body of the car. I got this Expedition first on a barter trade and was going to do the body work myself as a learning experience and afternoon project. But then I came across and got a second Expedition which is a 2002 Eddie Bauer 4x4 with an engine that needs head gasket work. I was not expecting to get this one and got it completely by chance (traded it for a generator I no longer needed) so when guy offerd it to me I jumped on it because I would have been happy trading the generator for just the seats, but got the entire car. This Expeditions body is immaculate and extremely well taken care of. It's also a 4x4 so what I want to do now is put the 2002 body on the 2000 Expedition frame but the 2000 Expedition is not a 4x4 the 2002 is. I dont plan on using this one to go off road in because obviously it was put on a chassis and motor that is not 4x4, so now I have one Expedition that is finished and one extra body and a complete chassis/frame with the 4x4 that has the blown engine. What I want to do with this one later on is fix the head gaskets myself and turn this Expedition into an off-road toy. I would use the non 4x4 2000 body on the 02 4x4 frame. Being how this will be an off road toy I was going to weld a roll cage on it and just weld some open doors on it and call it a day, but this body did not have the 4x4 option so if I was to do that how would I activate the four wheel drive? I'm hoping it's just a switch I can install or Mickey Mouse in and not something that has to be done through the computer of the car. I have worked on cars before and did a head gasket once but not too experienced with this kind of thing and just really want to do every thing correctly. My main question is will this work and if so how would I activate the 4 wheel drive when I need it?
