Drilling the Rear Spring Hanger holes to 1 1/8" is not going to be easy. No room between the spare tire well and the inside frame rail, I am only able to drill from the outside-in just fit between the lower quarter panel to frame rail. I rented an Angle Drill from my local TrueValue Hardware Store and I found my new Best Friend!
