Dana-Spicer would be the modern replacement style.
Ford themselves switched from the "ring" version shown to the Dana-Spicer model some time mid-Model A production. Today the ring style is no longer available but the Dana-Spicer Pattern is UNIVERSAL, even for modern cars.
To the point of being able to "mix & match" input and output sides - the cross and bearing paks of similar size units are all the same.
Like me working up a conversion to allow the use of the Warford Overdrive auxiliary transmission (which was actually produced for the 1928-29 AA to replace the "Dual High.") but in my case was being adapted to replace the driveshaft mid-extension used with the 1930+ AA 4-speed Borg Warner ******.
"In the day" this was done to parts and part numbers showing in Ford's 1948 era "Green Book" - the part numbers being Ford numbers (but made by Dana-Spicer)
This requires today a "mix & match" D-S universal joint - one side to match the Borg-Warner, the other side to match the AA driveshaft.
This may be akin to what you are doing. I can't remember spline-counts or sizing for the Warford application.
You can check out the Dana-Spicer site and they USED to have some engineering information. OR you can go to your nearest driveline specialist and he might actually have the parts in hand - or can get them.
Warning though - Dana-Spicer makes the odd sizes "irregularly." You may or may not find the part you're looking for (might be back-ordered) even though it shows in the catalog.
