69 Dart Radio Mounting Bracket

Hey guys,
I am in need of a thumbwheel radio mounting bracket for my 69 Dart. If you are looking at the rear of the radio, it goes on the bottom right side of the radio. Both my Darts had the original radio's removed long before I got them, so I'm not 100% sure of how it looks or mounts. I'm a fairly good fabricator, so if you have one that you don't want to sell, I would be willing to rent it to make a copy. Any help would be appreciated.
Thanks,
Martin
