in my travels i've seen a handful out in the wild. eons ago i bought a 74 W200 with a 440 that had a shorty w/ a slip yoke and a divorced NP205. the 440 and NP205 were absolutely how it left the factory, but i can't say with 100% certainty that the shorty 727 was there from the start, although it looked to be unmolested to my eye.
