I believe that the driver's side seems to be fine.
After pulling the drums off and inspecting everything, all the old hardware was re-used. Which I would expect should be fine. Although the self adjuster wheels on both sides look like the teeth may be a little worn.
The only thing that I noticed on the passenger side (one that was over-tightening) was that the self adjusting lever was not really in contact with the self adjuster teeth. So i pressed on the lever ect. to get it to touch, but it seems as if it is hit or miss with catching the teeth when I spin the self adjuster.
I went ahead and ordered all new hardware for the drums. Plan to just break them all down and rebuild with the new parts and see what happens.
Also, my access holes in the backing plates seems to be almost welded shut with a plug, although you can clearly see there are ports. Is there any way to get these opened up? I tried a hammer and a punch from both sides, and that seemed to not even budge them.
I took some pics for you guys to look at:
