I am going to install front roll pan. I cut off 2.5 inches of front of frame according to instructions but it still looks like I could cut off right up to rad support so it can clear, anybody else run into this?

Also I was going to use urethane one stage paint, do I have to sand in between primer and paint when it was sandblasted on the grill? it is just hard to sand the grill, that is why I sandblasted it in the first place.
