It might be considered a 133 or 135 wheel base, or go online to Advance Auto and look up what you might have. Hook tape on front of front rim and front of back rim and measure, if you measure the tires they might be different sizes and give a wrong measurement.

wheel base is center of the rim to center of the rim front to back....

so axle centers

Yea, but it's easier to measure by yourself if you hook it to the rims. As long as the rim diameters are the same size the measurement is the same as center to center.

Go to AutoZone instead. I have found that many parts stores don't know what they're talking about just because their computer lists something wrong. "You can't argue with the computer". Yes I can. Several parts for our trucks are listed wrong.
