Hi Julie, I'm pleased to assist you. I have checked the manufacturer's website and the length of this quarter panel is not mentioned as this is a direct fit replacement for the specified vehicle applications listed. We only have the shipping package dimensions which are (LWH) 30 x 14 x 10 inches. If interested in this part, use the link below to order at 63% off the regular price today while supplies last.

I measured diagonally 29 inches, from the point of the wheel well, to the opposite corner, which would sit above the bumper. The rear section is a radius. There isn't a place to take a measurement without figuring the geometry. I used this on a 95 econoline 150. As good of a fit as you can get on a replacement panel. Good luck

Hi, In as much as I would want to help you, I do not have the complete vehicle information to work on. We can only guarantee fitment based on our application guide. On the Homepage, please enter (complete) your vehicle’s year, make, model, sub-model, and engine type, and type the part's name in the search box. Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.
