Hello, I am re-doing the brakes on my 1973 roadrunner and have attached pictures of how the brakes are set up once I removed the drum on the rear driver and rear passenger side. Is there anything that seems to be missing or can they be assembled just like this with new parts? My only concern, from watching videos, is the parking brake lever and cross-bar and whether those should be on one of the drum assemblies. They were not there when everything came apart and the pictures show that as well. Any clarification is appreciated, thanks!
