I'm upgrading my master cylinder on my '55.1 Chevy p/u 3100 from original m/c to the dual m/c. I've acquired a drum/drum m/c to install, but I'm having a hard time determining if proportions and/or residual valves are needed or should be used. Placement of my new m/c will be the same place using the bracket I got from Precision On Line (POL). Please advise.
