I need a little help sorting out the differences are between a Model A driveshaft and a V8 driveshaft. I do not at the moment have any disassembled torque tubes around to allow me to see for myself so I need a little help. As I understand it a Model A uses a 1 piece driveshaft but a V8 uses a 2 piece driveshaft with a splined stub attached to the pinion and a splined coupler to attach it to the driveshaft, correct so far? If those 2 things are true then can that “pinion stub” be used on a Model A differential or must a V8 differential be used? These questions all pertain to installing a Borg Warner overdrive into a Model A.
