Are those 11" drums?
The service manual images I have do show a few differences from what you have set up.
The anti-rattle spring on the strut just below the wheel cylinder appears to be backwards; the tab/tail of the spring should be against the tab of the shoe right below the wheel cylinder piston, on the outside of the strut.
The spring running from the stud the anchor plate is on to the rear shoe should be on top ofthe spring running to the front shoe. Could it be interfering with the adjusting cable? Order of items over/around the stud should be shoes, then anchor plate, then adjuster cable, then front spring, then rear spring.
The end of the adjusting cable, where it hooks to the adjusting lever is wrong; the hook goes in from behind the lever, as you have, but that rectangular frame should be outside of the adjusting lever. The lever is 'captured' between the spring hook in the back, and the metal frame on the outside.
I'm not sure any of these could cause the problem you are seeing though.
