I went with the CPP kit easy install and did not change the stance of my truck. I took my time and it took me about 3 hours to complete. I also installed thier power steering kit and it wasn;t that hard either. here is a pic of the disc conversion when it was through. I went with the 5 lug conversion. I used 69 corvette 15+ rims and I did not have any clearance issues with the calipers [URL=http://rides.webshots.com/photo/2542598820107361323oapFOW][IMG]
