Not sure what exactly you have for rear fixtures, but the original type are grounded through the housing, and then what ever the housing is mounted to. Simply unbolting things and scrubbing to bare metal might make it all fine.
I got sick of chasing ground issues and added some of my own. Put a self tapper in the bracket between the stop and tail bulb that holds down a dedicated ground wire that runs to the frame. Also added a wire from the frame to the bumper (my bumper is a farmer-made thing that also supports the lights.
You have a 12v test light? Pretty easy to confirm or debunk the bad ground theory with one. Feed it with 12v, start poking around on the path that ~should- be grounding your lamp housings.
