07 classic vs non classic
 

I juz ordered a level kit for my truck but i did not realize that i had a classic. In the order it says "will not fit classics". Can anyone help me w the diffrence of a classic and a non classic Also is there a way for it to fit? Who makes a nice kit for the classic? Preferably 3.5 in front and 2" in front. I hope someone can help me out. Thanx James Jones
