When the road received the Super 7s I had a chance to shoot them alongside the GP38s. Super 7 Ms were much redder. But, the orange look is mostly from fading - the MGA Ms on everything else were definitely red, but with a hint of yellow - sort of a vermillion-red, the same as red taillights on a lot of vehicles. Since there's no such thing as a perfect color match, I'd suggest applying one M to a black piece of plastic and seeing how it looks on that first - and view it under daylight and under layout room lights.
