The GenII console is a common 12V heater/cooler here - about $35AUD. The tray it sits in is mostly plywood. The portion that surrounds the emergency brake is original. The MMC console came from a local junkyard here (Australia) that I cut down.

I kept the original console. The government here does not believe in private property. Modifications are frowned on. For example, my SWB here has two side by side fold up seats in the back. I've removed one, which is illegal unless I get an engineering certificate to prove the mod is okay. When I sell this one, I'll have to undo my modifications. 1984!

Oh, thanks again for the pix tutorial.
