New guy lookin for help about replacing old grill.

Im a young 16 year old guy who doesnt know much about workin on trucks and ive been browsin all over this forum gettin overloaded with info. and i love it!!! I have an 05 DC Prerunner and have been looking at the grillcraft black mesh grills for awhile online. Now i want be gettin one until summer; and thats if everything goes right, but i have a question about the install. i know you can bolt the grillcraft over the original, but it obviously looks better to cut the old grill out. so, how exactly do you go about cutting the old one out. (what tools, difficulty level, process). Thanks guys!
