I'm new here looking for some info. I have 2007 Charger R/T Daytona recently in an accident and will be totaled. I need to know what I need off of this car before I send it to the junk yard to be able to put the 5.7 hemi in the Grand Cherokee. Do I need the wire harness, computer etc. And since it's a 4x4 will this hemi drop in and bolt up to the transmission/transfer case? I just need to know what I need off this car before it goes to the junk yard. Any info is greatly appreciated. Thanks!!
