Outer Limits 4x4 Board

Need to source a waterpump housing for my hj45 ute. The outlet where the bottom radatior hose connects has cracked off (was made of alloy, possible aftermarket replacement?). Motors a 3.6L H series diesel (model before 2H).

Does anyone have a good secondhand one or know were to get a new housing?
Ive tried burson, repco, terrain tamer, toyota themselves and assorted different wreckers and all i can find is a late model 2h housing which is slightly different from one wrecker who wont let me return it if it dosent fit......

any help would be great!

Let me have a look in my stuff tomorrow, i had a couple of H's before ditching the lot, might have one laying round.

want to snap a pic and throw it up so i can tell for sure if the spares i'm thinking about are the right one?

^^^They should be able to help you out, I've never had dramas sourcing bits for my H motor through them.
