I have posted on this topic before but I now have more information. I have a Borg Warner R10 overdrive set up in the torque tube for a model A. Unfortunately a coupler is missing and the OD is worthless without it. Apparently what was done was that the the slip part of the slip yoke (yoke was cut off) 16 spline Ford 3 speed transmission (the OD pattern is the same) welded to a stock 6 spline V8 coupling. This coupling attaches the overdrive to the differential, there is no actual driveshaft between the OD and the differential. Somebody made quite a few of these (rumored to be Lloyd in Ohio) (Not Bert In Vancouver Washington, his are done differently), and there has to be some of these couplings kicking around in folks stash of parts. I know that now that I know how the part was made but the cost of the parts is close to $200 and then I have to have it welded. It’s just not worth it.
