Does anyone have plans for off-road vintage go kart (as seen @ gokart alley @gopowersports!)?

They don't have the plans for it. A father-son called Go Kart Alley are making replicas of the old Manco American Express karts. Similar sized, but a bit longer to accommodate taller riders. https://www.gopowersports.com/go-kart-kit-frame-xl/
