Centerline Wheel Thickness

Yep, 3.5" skinnies are different than the 5.5" wide and up wheels.

If you need lugs for the wheels, this guy from E-bay is great.

He made me a split set of open end lugs for the thinner rear/thicker fronts and they are nice. Just took a quick e-mail and he had it done the next day. Prices are better than most anywhere else. 20 lugs/washers were about $28 delivered.
