1 Vintage Air’s SureFit systems feature a Gen-IV Magnum evaporator case at the base of the system. The Gen-IV is fully electronically controlled and uses a high-flow evaporator coil. You can use the included cable converters for the OE dash controls, or fit any one of several Vintage Air control panel kits to your custom interior. Note the ’65-’66 Mustang kit shown here is the complete kit. Evaporator-only kits are available if you already have your underhood components.
