Let me throw another question into Elrod's great thread:

Which of the leakless pumps still use the contact point between the end of the shaft and the inside of the head for end-play control like the original? If it is not needed on some designs, why have the long stub beyond the impeller?

I bought a leakless with a locked shaft 3 years ago (don't remember from who) and it was a bit too long to fit into my new Brumfield head, so I just sawed off the useless end of the shaft. The missing shaft stub didn't disrupt the water flow and it was way easier to get the pump in with the radiator in place.
