The Magnum and the last Viva (the 'HC' model) had the same body.Magnums came in 2 and 4 door variants with the flat front. Think there’s also a variant using the coupe body. Main difference aside from the droop snoot was the interior which was a fraction posher. At one point I had a two door and my father had a 4. Very useful when working on the car, if I couldn’t figure out how things went back together, I took his apart.
