As far as a body goes though, there aren't any Holden's with a full chassis unless you go back to the real early stuff, so you would have to engineer in mounting points. Although, I do know where there is a Crown ute that would look OK jacked up. I guess that would be full chassis the same as the wagon. I saw a pic of the hatchback a little while ago and it was full of rust. I don't think it is even running any more.
Cept utes , one tonners and panel vans in the HQ-WB series
I know where there's a Disco chassis with rebuilt eng/trans/diffs sitting if your keen
