Might not make much difference but I moved the license plate from in front of the radiator for a little more cooling to the front bumper using a rear license plate holder.
Here in San Antonio, Texas the temperature hit 110 degrees today. I ran errands this morning in the Roadster when it was just 95 degrees. Grateful that Texas doesn’t require front plates on “Antique” registration.
Mine was mounted above the bumper using a rear bracket when I got our car. I cut the sloped area of the bracket so it would clear the bumper clamp. That allowed me to mount it in front of the bumper with the plate lower.
