Transmissions Humps and Tunnels

[RootBeer 6117]

I'm working on my 49 AD,some time in the last month some one posted pictures of how they laid out the sheet metal for a curved tranny tunnel.I am trying to explain to a HAVC class what I am wanting as every one know a picture is worth a thousand words.
I have tried the search engine with about as many key words as I can think of and still have not found it.
Careful what you word you use on google for this you might find something you don't want to find.
Thanks Joe
