[Mgb-v8] Fwd: Shortened water pump

[David Kernberger]

To all,

	For what it is worth, I am with Darius.  It seems to me that 
either this short pump will require a pulley with a different amount 
of offset, or the other pulleys in the system will also need to be 
changed to match.  All pulley grooves for a single belt must lie in 
the same plane.  I even wonder if the short pump might locate the fan 
in the old belt plane??  Or maybe awfully close?  Am I missing 
something here also???

Cheers,
Dave K.
