The whole rear assembly was all together with drums on & green clips holding them & orange plastic holder keeping brake cables together on complete assembly. On the Dearborn cars I worked on I have seen KH on 1 side & bendix on other & hardware different on brake cylinders between the 2 with flat bolts on 1 & sunken head bolts on the other & both have different ink stamps date type marks & both types rubber adjusting plugs. I see more drums without extra hole type than other version on Dearborn cars. Also later they started stamping date on bottom outside backing plates in the metal.
