Been there with a 66 Barracuda, 413/727 straight axle and ford 9'', 2nd gear would turn you sideways if you weren't paying attention as the new owner found out. Found it a few years later and it was tore up and they had taken the hood scoop off and the engine filled up with rain water, ruined the carbs on the Tunnel ram and engine owner was was going to fix it someday.....year later I heard they scrapped it.
