Attending his first model-car contest, Gary Plennes brought his tricked-out Revell 1/24 scale 1970 Challenger T/A. For a restomod feel, he upgraded with 3D-printed wheels, tires, brakes, seats, belts and buckles, front splitter, steering wheel, shifter, and exhaust. “It’s the car I would build if I had the cash,” Gary said. He painted with Createx acrylics and flocked the interior carpet.
