Greg, Had a similar problem on my Challenger. I took my springs to a spring shop and had them re-arched for an extra 2 inches (MOL) of height.
Your other choice might be to replace the wheel with something with less backspace. Would bring them in under the fender better. (Re-arching would be cheaper!)
