Help with cutting and flaring ALL wheel wells on 1964 Barracuda

Thanks for the replies!

So get the wheels and tires first but my question then becomes this.

So I put the suspension on. I try to put the wheel on. As I'm lowering the car back on the ground I notice the the wheel is to wide. I then can no longer lower it enough to get the cut.

Or if it's to talk and I can lower the wheel it would be hard to find where to cut because the wheel would be on the inside.

Now with the rear I know I can put that on jack stands so I can measure the center of the hub to know where to cut.

On the front though... I'm not sure to get the from under load to measure it to know where to cut?
