[Mgb-v8] Fwd: Shortened water pump

[Barrie Robinson]

David et al,

I did not install my engine (no facilities for large lumps).  All I 
can say is that it was, and is, installed and works.  The chaps who 
did it listed all the problems they had with the installation (to 
justify their invoice!) and this was not a problem area !!!!!  If 
anyone wants I can take photos and send.
