so i figured out the rear valence i have for my dart is twisted just a bit. Been trying to figure out how my quarters and the tail panel and everything else was square, any way it was measured. but when i put the valence on, it looked like the right side was higher than the left. So i finally took it, measured the valence for squareness and its out 1/2 an inch or better. and in a weird twist that I lack the skills or knowledge to correct. So time to get a different one
