[HELP] Custom idea - Need tips

Hi guys! After reading yet more material about the amazing Ford Maverick Hollywood Berta that raced on Brazilian Stock Car in the 70’s, I couldn’t hold it anymore. I need a model of this car.

Just for you to know how awesome this is: The rear tires are F1 tires with 380mm (15”) of width. Look at the air intake at the hood and the NACA ducts to cool the brakes, and that humoungous rear spoiler. The engine was the V8 302 from the Mustang Boss (the same engine of the Brazilian Maverick GT), but with Gurney-Weslake cylinder heads, exactly the same that equipped the GT40. This car is beyond awesome.

No one really knew its power, but the mechanic who built and tuned the engine estimates it on more than 400 hp @ 6500RPM. It won almost everything where it raced.

So, I want to make a custom of it, since I can’t find a model of this car. However, I don’t know how to make the huge rear spoiler or the front spoiler contiguous to the wheel arches. Any tips?
