2001 WJ 4.7 motor swap

[macgyvr]

My dad has done something and now needs a motor for his 2001 WJ with a 4.7. I'm looking to source a junk yard motor right now. Once I get it, is there anything that I need to know or watch for in doing this swap? I've swapped motors before but know sometimes there are tricks...like the external torx on the 4.0s...

mac 'thanks' gyvr

Pretty much have to remove the front bumper and grille to get the radiator out.
