I have 2 Jeep Wranglers here, noticeably different - my guess is age.
The newer one has the following measurements:
27.5 axle to axle 25.5 center line of wheel to center line of wheel.
Going from the outside edges of the wheels 32.5 by 38.5
Overall length is 45"
It looks similar to the one for sale at Walmart, but doesn't have the side mirror extensions on the windscreen frame.
