Where to get Gas Tank Mounting Tabs??

Does anyone know where to get fuel tank mounting tabs for a 73 Dart? The Swinger I am working on had the trunk replaced and the guys that did it did not save the tabs that you use to put the J-Bolts on to the straps (or the spare tire hold down bracket either). I need to get a pair of those tabs pretty quickly...Trying to mount the fuel tank this week in order to get the car out of my shop. Got another Customer project lined up...

Thanks
