I'm almost sure that most of the B body Dodges from 1963 or 1964 production cars to 1970 have 119 measured wheelbases Not 117 inch as advertised, just like the 1963 Plymouth B bodys where advertised to have 115 inch wheelbases, not 116 like they had On another subject, most of the Dodge B body driveshafts are longer than the same year and application Plymouth driveshafts The same year and size motors and trans. from both B bodys are interchangeable from one brand car to another My point is the wheel base length differences are behind the trans. crossmembers
