If you are talking about the nipple that the heater hose attaches to that screws into the intake manifold, any auto parts supply should have them. Take your old one in or just get a good look at it before you go. I think there are only two primary sizes.

On the intake side 1/2 npt

On the hose side, one is 3/4 hose and the other is 5/8 hose

The one on the intake should be the 5/8 hose

5/8" on intake, 3/4" on water pump.

5/8 = 15.875mm
3/4 = 19.05mm

$5.99 plus shipping at Ecklers, wow! That should be 59 cents at any auto supply.

NPT - national pipe thread- fittings maybe hard to find on your side of the pond,your best bet may be to remove it and use that piece on the new manifold if you can.I could send you one,but it would take weeks to get there!

jotto - Do you have any chain parts stores over there? They would be able to get you something like that, and even though NPT isn't standard there, they should be able to get it.
