Help with cutting and flaring ALL wheel wells on 1964 Barracuda

Hey FABO! I posted recently about performing a radius cut on my 64 cuda, helped alot some good stuff there. I thought I was ready to do that until I came across pictures of a 1964 barracuda built by oly express and it was used as a Lemons car. With that said! I actually think this barracuda is pretty awesome looking, and i would like to cut my wheel wells very similar to it, and put on larger wheels.

I hunted this car down to get as much info about it as possible and i came up on some good info. I even sent the Oly Express team a message but there last update was Feb. 2012, chances of a response?? unlikely?

For the front fenders it looks as if the went along the wheel wells "slight fender flare" with a sharpie, im sure made more of an accurate measurement and then cut it. then it seams like they lined out about an inch of theyre cut and then flared it at that 1" mark.

for the rears, it seams as if they just, measured the front and applied it to the rears but, used the wheel wells factory openings on the bottom, so in a way they just gave it more of a rounder top.

My cuda is currently stripped completely and in epoxy primer. I feel right now is the best time to do a modification like this. Problem being I do not have any suspension in the car, or wheels of course.

My question is...

Is this a mod that i can do on the veihcle at this point? OR, do i need the vehicle to have all the suspension in and the wheels I intend to use on the vehicle, with the car mocked up to the stance i would like?

Only problem i see with the second part "mock up version", im sure a larger 18x7 wheel up front will not even clear the fender at all, potentially hit the fender lip as i lower the vehicle or try to install the fender.

Im kinda thinking of just doing the cuts as I feel they where done, and basing it on the theory that they where done for a good clearance of 18" wheels.

Question 2...
How do i get such a parfect flare like they did in the photos? A fender roller from eastwood?
Dont know if that roller would give me these results...
I kinda want the flares to be bigger, I will attach a photo of a picture i found online of an examle flare. Not that big up front, but maybe 75-50% smaller.

Thanks guys!!
