G'day Alexfine,
There's a lot of "what ifs", but another idea may be a well padded plywood box on a small trailer. Not too bad idea if:
You/mates can get/make a trailer for cheap. Trailers under 750kg capacity are self assessable (in QLD at least). Maybe you have other uses for said trailer to justify it? Hopefully a trailer hitch kit can be obtained from the wreckers for said 323?
If you make the trailer, give it a sleek profile for less drag on the highway!
It would be dead easy to lift the dob onto such a low height. Perhaps it gives you the possibility of carting a larger model in future, for no extra effort (make the plywood box big enough for a 16" perhaps).
Just a thought
