Hy Joiner Transit, I was just looking at some of your pictures, I think I am seeing a rear brake crossover line on the outside of the backing plate. If that truly is the case the part numbers I gave you for the rear brake wheel cylinders would be wrong. The possibility of parts swapping on a truck that is over fifty years old is always a concern, we must know what parts are on the truck in order to obtain the correct replacement parts.
That is totally understood. Is that out of the ordinary for a 1966 S-69 to have that since you thought it should be the other style, or are you meaning by parts swapping meaning swapping the rear axle at some point? What are the part numbers if it were the other style?
