ok thats a negative on the alternator.
How about this for a coupler housing:
This I hope gives you an idea of what I am trying to accomplish. The big thing was that I had to shorten the shaft a little and this picture helps show how I think I can make it work. Below is just the shaft stuck into the coupler with a sealed bearing and the cover. I need to make this thing solid so that there is no slop in the shaft.
