66 273 radiator/fan shroud dimentions

Having had a recent success on fabrication some hard to find bits and pieces I was thinking of attempting another but bigger project.

Looking for anyone with fan shroud that came with the factory AC package in the early Valiant/ Barracuda that can get dimensions to create a detailed drawing. I believe from the collection of photos I have found that it is a two piece steel box.
My radiator has the support mounts on it and I could make a lot of "guesses" and start fabin' something but I would like to make it as close as possible.

Anyone out there have one of these boxes and the time and inclination to get all "detailed"?
