The original design. The ultimate tribute.
Step back into the drafting room where the legend began. Printed on the back in striking high-contrast blue line art, this tee features GM factory blueprints detailing the iconic lines of the classic squarebody frame. Up front, it’s anchored by the clean Squarebody HQ logo, making it an absolute must-have for the builders, restorers, and purists who respect the original engineering.
Crafted on a pitch-black, ultra-soft combed ring-spun tee, it offers a lightweight feel with just the right amount of stretch—engineered for long nights in the shop, hot summer drives, and weekend truck meets.
