All I did was relocate the leaf springs and use a 6.5" backspace wheel. No need to widen the wheel wells in this car, they are huge from factory. If I wanted I could've fit a 14.5" wide tire. If I widened the the wheel well and went to the frame rail I would gain another 2 " . Either way it would've looked like a full tub car.
Did you mini tub it?
