When we spoke last evening, you mentioned the adjusters on the wheel cylinders. I can see the amount of over adjustment of the rear shoe in your photo. Unfortunately, I don't have a picture of my driver's side, but do have a passenger side. Note how the arc of the shoes follow the backing plate in my photo. Look at where the arc of the shoe is in your photo. Again, there is no way the lever can engage the extension with the wheel cylinder adjusted that far out on the rear shoe. Bring that adjuster in, manually operate the cable watching for the cable to pull the lever, and watch for the lever to move the forward brake shoe. If this works as it should, maybe the drums aren't correct. If you have to adjust new brake shoes out that far something isn't right. Did you replace the rear brake drums? Maybe you inherited the wrong drums............ I'm just thinking out loud here.
At this point, we need to confirm that 'all' of the correct components are in play. Let me know, thanks.
