Hey guys,
If it's this wagon:

....it's a bit of an abomination. It was made using a Ford Falcon (XD-XF) rear roof section and was grafted on.
I have read they built both two or three prototype wagons. I read on
http://www.leylandp76.com , that one somehow ended up with Ford, where it was tested against their own cars, while another ended up in private hands, while another site said that two were destroyed and one was sold. Apparently the two that were destroyed were mocked up in fibreglass, while the genuine factory item was steel.
The factory item was used as a parts getter around the Zetland plant, then sold to one of the lucky chumps who bought a Leyland Force 7V. Interestingly, the plan was to use a one-piece clamshell tail gate, something that would not be seen in rival Ford or Holden units until 1978-1979, however the prototype had a then-traditional two-piece tailgate, interestingly with the lower tail gate adapted from a HG Holden item! It is still in private hands and looks like this:

There was another that was designed to be a replica of the prototype. This also used a Falcon rear roof section, albeit from a more contemporary (to the P76) XY Ford Fairmont wagon. This one was a lot more successful in looking good (for a P76) -

There have apparently been a few different wagon replicas, but they all use a standard sedan rear door window profile, while the factory car had a more upright rear door window. Conversely, the factory wagon has a very sleek back window line which however made it useless against the more upright and therefore space-efficient wagons from Ford or Holden... so maybe it's for the best that the replica-builders used Ford stuff!!!
