Sue, think what ever one is saying must be so, the bracket is bent. I also had somewhat of a time with mine (one of Ron's). What I have done in the past, is just start the bottom two bolts to hold everthing in place, then pressing in the center with the knee, the curvature would open up enough to get the license plate bolts started, then tighten them evenly. Have it warmed up to make it more supple. That said, I think maybe bring the bracket forward will help, but try this before you go to the trouble of taking the front cladding off.
Greetings, Earthling. We come in peace... Never mind "Paris to Dakar", the VehiCROSS looks ready for the Martian desert.
