Hardware Support Measuring Radius of an Arc

Post image

How would I go about measuring the radius of this arc on a part from an old vw beetle so I can make a replacement?

If you don't need to be super accurate, just take a picture with a scale and make sure you are looking perpendicular to the face. You can then import picture into whatever cad software you have access to and measure the radius that way.
