I think that A100 vans and trucks also had short shaft transmissions in them. They had a lug on top of the tailshaft housing that the transmission mount bolted to.
Edit- I just went and looked thru @Jim Kueneman thread on his A100 truck, and the pic of his transmission shows it to be a ball & trunnion style. Not sure if the later ones would be a slip yoke, but I seem to remember my buddy having a V8 truck with a 727 and slip yoke shorty transmission.
