I haven't got any I can sell you, but I can tell you that the badge on the back is the same as on p/vans and station wagons, different to the sedan type. The bonnet should have small (1" approx) letters H-O-L-D-E-N across the front, and the guards should have a diecast "spear" maybe 18" long as you suggested.
You should be able to find examples of each in the Members' Cars area if you do a search there for utes. But in the meantime here are a couple that might be useful...
This ute belongs to 'paddyfc58', which sounds appropriate for a bloke in Ireland
This one belongs to 'fc_mad' in Tassie.
cheers
