about a year ago I added a set of steel leafs from a 2000 Astro so i could tow a small camper without problems and i don't plan on lowering the back end because of that.so if my front end is 28 and the back 30 i can deal with that. Thanks for sharing your views and info. I am glad i did this and found the lower ball joint so loose instead of finding it out on the road.
