So, I bought a ready to go Borg Warner overdrive for my Model A but it turns out that the 18 Spline X 6 Spine coupling is missing. This coupling connects the rear overdrive output shaft to the pinion stub shaft and the OD is useless without it. I do not know if this coupling was OEM for some vehicle or if it was custom made by the overdrive kit manufacturer. There was a fellow in Longview Washington that made a couple thousand of these so there must be some parts floating around.
