What is the WMS to WMS measurement, and year truck?
To get an accurate measurement I remove the wheels, set the steering wheel to straight ahead, put a straight edge on both hubs so they're as close to center up and down as you can and level to the ground. Then measure the width between them both forward of and behind the axle, then take the average.
