Jack constructed a rollcage from 1.5-inch DOM tubing and sized it to still allow the use of either a ragtop or a factory hardtop. The interior was modernized for creature comfort and safety. Mastercraft highback seats are mounted to the lower part of the cage, and a Tuffy console provides lockable storage between the two. Three-point seatbelts were also installed and tied to shoulder tabs on the B-pillar. Behind the Mastercrafts sit a RedTop Optima battery and a rear floor-mounted heater.
