Rear drum setup...is this correct?

[72c20]

Ive just redone the rear brakes on my 72 c20, new wheel cylinders, shoes, and drums and i can feel the truck pulsing slightly as i slow down (not the pedal), and the right rear locks up while driving normaly. I put them back together exactly as they came off, but im not sure they were ever installed right in the first place since they never really worked. Every piece of the braking system on this truck is brand new except the proportioning valve and a few of the lines. Ive bled all four corners numerous times and spun the adjusters in and out, but nothings worked yet....I took a couple pics for you guys to see if ive set these up correctly...pics are of the left side
