I don't think its that hard just time consuming and a lil expensive. My friend Felix here in Miami is currently working on finishing up a project of his. And every one knows that he is the man when it comes to a diesel conversion, and horsepower in excess of 900. He just finished a Ford Ranger conversion to a 5.9l Cummins with twin turbo and supercharger. And is almost done now with his LLY into a 2005 Cadillac EXT. He is not real big, but when it comes to perfomance and racing people flock to him, I guess thats why he started putting 24.5" rims on regular 3500, F-350, and all other duallies out there since the 90's. Just a lil input
