It wasn't a body re-design, just deletion of pressed gills into the side panels. Probably done in preparation for HJ, but definitely NOT HJ bodies. If they were HJ bodies they'd also have amongst a few other bits and pieces:

Side strengthening ribs complete with captive nuts for intertia reel seatbelts.
HJ console or seat seperator mounts.
HJ cowl panels (for HJ bonnet).
HJ dash panel.
HJ firewall.

As I stated A09 appears on existing production broadcast sheets. Elizabeth body plant was obviously capable of doing it by the photo of those vans on trains. Just need info for Pagewood body plant and Acacia Ridge body plant. How much they cost I don't have documentation for that yet, and I don't expect it to be easy to find either as most vans were probably sold out of stock and dealers would have arranged fitment to those.
