Engineered to run 9.90 to 7.70 for customers with older body styles (e.g., '41 Willys) who want a late-model, high-tech chassis. Also ideal for Super Gas, Super Comp and brackets, our nostalgia chassis fits the 1937-41 Willys coupe and other popular bodies. (Its adjustable wheelbase adapts to a variety of "fat-fendered" nostalgia cars.) Double-rail construction ensures ultimate strength. Offered with 4-link rear suspension and either Mustang II A-arm or strut front suspension, these chassis kits include suspension brackets, mild-steel double frame rails and roll cage. (A 4130-chrome-moly version is offered on special order.) All Chassisworks chassis can accommodate NHRA-required mufflers with little modification. Multi-colored assembly drawings and instructions are included with every chassis, or can be purchased separately.
