Since the cars (444-544)are probably most related to Chrysler/Dodge/Plymouth and maybe Studebakers, of the late 40's, I'd look at photos of dashboards of any of those cars. I have a small heavy metal panel, about 6 inches long, which came from a '49 Plymouth Wayfarer I found in the boneyard. It attaches under the dash. There is room for 3 or 4 switches, and it looks like it belongs. In a'47/'48? Chrysler I also found a really cool underdash panel. It had a beautiful engine turned metal pattern engraved in it, and was about 12 or 14 inches long. It now lives in my '58 Duett. If you didn't know the cars, you'd swear it was factory installed. Go forth and scrounge!!
