What does it take to put a 2001 motor in a 2002 frame. 1. Does the motor mounts line up also head mount? 2. Does the exhaust bolt right on? 3. does the sub frame and airbox mount up without mods? 4. What the hardest part and what does it take to make it work? I would like to hear from someone who has done this thier self to get first hand info. Thanks alot everyone.
