Sectioning an aftermarket fender to fit?

[lyrikz]

I saw a post on here where a guy was fitting aftermarket fenders, and one of the fenders he had to cut a line in and add about 1/4 of metal or so. I think it was roccrawlin that had that post. Im looking to see if i want to go this way or just sell the fenders and get a factory fender.
My only issue is i dont want to sell this problem to someone else and i dont mind doing metal work.

Anyone know what im referring to? It was the front of the fender and he was trying to get the hood and fender gap perfect.
