I am working through my local NAPA and Carquest parts stores to locate new wheel cylinders for my early 1947 GMC EC-302 truck. It appears that front cylinders are available. It does not appear that a direct replacement rear wheel cylinder is available. Carquest asked me to find out if a 1946 1 ton rear wheel cylinder is a possible/suitable replacement. Does anyone here have experience with interchange of wheel cylinder parts? Also, would it be a good idea to use the original type DOT brake fluid or would the synthetic brake fluid be a good update? Any help on these questions is appreciated.
