Lee,

I bought one from Vetus http://vetus.com/. There online  catalog is not much 
help, but I an using their Bullflex coupling and it  works great. It is 
metric so it means taking you shaft to a machine shop  and having turned so 
it will fit in the coupling. It permits for a 2%  misalignment up to 3000 
RPM. Since our shaft RPM is around 1500 (Atomic 4  1:1 or diesel ~ 2:1), it 
is well within the range of operation. Even with  this device, I have the 
engine aligned within the .004 tolerances as  recommended by the engine 
manufacturer. Remember that this measurement is  taken with the engine off 
and no load. With a diesel replacement engine,  the engine is mounted on flex 
mounts. Because of these mounts, when the  engine is started and and placed 
under load [forward or reverse] the  engine moves and the angle between the 
engine and the shaft changes. It is  for that very reason that I think it is 
essential to have a flex coupling  if the engine [any engine] is mounted on 
flexible mounts.

thx Mike,
Just more good info convincing me to go this route. Means I gotta get the  
shaft out...again....to be shortened to accomodate the flexible shaft coupling,  
but sounds like it will be worth it.
