Rob,
  I do not know what the price differance would be but I = suspect=20 that you
need to buy a "IVO" adapter plate with the correct drive lug and = bolt=20 size
to fit your "RWS" redrive prop hub.........I suspect that "IVO" = can pick=20
one off the shelf........To have "RWS" (Tracy) rework your = redrive=20 would
probably be more expensive.........Call them both and find=20 out.......FWIW

Rob,
   If your "IVO" is like mine then it has an = aluminum=20 adapter plate that bolts to
the  SAE 2 redrive hub with either 3/8" or 7/16" (allen = head=20 internal wrenching)
bolts then the "IVO" blades are sandwiched between that = adapter and=20 the outer

drilled to the standard SAE 2 bolt spacing and for whatever=20 bolt and drive lug

True Buly, except I don't know why prop hub = thickness would=20 be a factor or do you mean prop thickness at the=20 hub?  
 
 The rest of it is:  5/8" drive lugs, 3/8" prop = bolts=20 (unless 7/16" ordered as an option)  SAE 2 hub spec = covers=20 everything else.
