Mark, you will not believe how much better your truck rides and handles with the bars and coilovers. The panhard bar eliminates any sway and you can get springs in any rate. I have two sets--one for empty super smooth cruising and one for loads or trailer pulling. It's a snap to change them out. One thing you might consider is to use ladder bars instead of 4 link because they are much simpler. The 4 link is better for race applications since they are infinately adjustable and the setup can be dialed in for strip conditions. This is not necessay for street or regular performance. If you want to see a picture of this setup on a frame just like yours you can go to the Chevy Duty site and look at the "frame mount gas tank" posting on the first page. It's about a gas tank but shows the ladder/coilover setup.
