Dave,
I was born and raised in Midland! My dad had a 65 Chevy truck when I was very young. As far as the glass vs. steel fenders, I would go with the steel. You live in an extremely dry climate and future rust should not be a problem. Also, the fiberglass does not hold up well when it comes to rocks being thrown from you tires. A piece of gravel thrown from your tires can leave a star in the paint.
