Trying to find the right wheel bearing

Hello everyone, I'm trying to find the right wheel bearings or wheel bearing kit for my 1972 plymouth duster. It's a drum brake car and I can't seem to find a for sure kit or wheel bearing for my car. It managed to grenade itself not far from leaving work so I had to limp it back as I didn't want it to turn into a 3 wheeler. I can't take the car apart to see the part numbers as I do have it at my work and I do need it to move under its own to shuttle the work trucks in and out of the shop. Plus we don't have room or Jack's as my coworker has his mustang ripped apart already. So any help in the right direction would be very appreciated.
