I am selling my project jeep. I took out the 4.2 engine, trans, and transfer case, which will go with the jeep. I have a 4.0 engine, trans, and transfer case sitting in the jeep now. You will have to fabricate engine mounts and trans mounts. I have the wiring harness and ecm from the other jeep that goes with the 4.0 engine. Any questions call Ken 551-427-1047
