Ok I have a 2003 Dakota slt 2wd that has a awesome body on it that needs a motor and trans...now I have a 97 Dakota with the 5.2 v8 magnum with trans......now can I use the 5.2 for my 2003 if I use the pcm and harness for the 5.2 and if anyone knows change out the gauge cluster along with the wiring under the dash or would I just need the engine and trans harness??? Reason for the 5.2 swap is cause got the whole truck free with the 5.2
