Try Heidts, TCI, Fat Man Fabrications, Jim Meyer Racing, etc. Any of these companies can set you up with a Mustang II style front suspension with coil-overs, sway bars, etc. Don't forget the rear suspension too, new components and a rear sway bar will help you achieve the spirited driving you're after. My 55 2nd series is set up in this manner and it handles like a go-cart on the twisties.
