In a word Search. The topic is heavily covered in the archives. I posted with full specs because *that* was hard to find (not many ppl posting what they actually got, just what should work). The -6 seems to work pretty well. Since I dont and didnt ever have running boards I can't say how well it would work. And yes the - offset pushes the wheel outward from the well.

I'm still very pleased. No noticeable difference in mileage or speedo. RPM's before match what I show now. And they look alot meatier.

Hope that helps.
