During my little strip down, I ordered a new water pump to fit. Unfortunately iv been sent the wrong bloody one.

Can you advise what one i need, or what year to order from?

The one i've been sent bolts into the holes around the top and on the bottom left hand side, but the bottom of the water pump doesn't stretch down far enough.  Its noticeably smaller than the one that came off.
