Texman, here's a picture of a '37 Cad/LaSalle transmission on ebay.
http://shop.ebay.com/?_from=R40&...ansmission&_sacat=See-All-Categories Street rodders used to remove the tailhousing you see in the picture and bolt a Ford torque tube type rear mount/bearing retainer directly to the back of the transmission case. The Ford u-joint would then be mated to the shortened and resplined Cad/LaSalle tailshaft.
It's a very simple machine shop procedure to respline a shortened shaft.
That is the same concept your project would use.
