I used a Flywheel from a '06 4.8L or 6.0L, they are the same flywheel. It is raised to make up for the .400" difference. you do not need a spacer. The flywheel can be had new in the aftermarket for about $100, Sachs NFW1050. You will also need an extended pilot bearing. I used one from NAPA, 6302-VSP43. On the flywheel I removed the pins, and had to make the holes slightly bigger on the pressure plate to accommodate the metric bolts used with the newer flywheel. I also used the stock exhaust for the 5.3 and used some misc pieces I had laying around in the garage to fit it to my existing exhaust system. I will try to post some pics tomorrow.
