The fenders I have are an accident that's already happened on numerous occasions. They were only good for what I'm using them for.
I hung the passenger fender and dimensioned for the drivers side door and hung the drivers side fender. I sat the hood on and made sure everything seems square.
Then came the only actual fun. I used the laser and located a level line and a center line for the modified wheelbase. Relocation will be 10" forward.
I installed tape on the lines that will need to be cut. The area painted in black will need to be removed. Notice how well the leading edge of the cut line aligns with the original corner of the front fender above the bumper. You can achieve this by measuring 10" forward on a level line from the wheel well and making that your cut line.
