...And the plot thickens!

The guys swears it will fit a 1440. Another one of my concerns is that even if it fits, do I have to be concerned with the RPMs making sense? You know...that thrower spinning too slow or fast? Anyhow, if I end up getting the green light here that it will fit, I will be sure to document how it all works out for folks in this situation in the future!
Thanks!
