I sent my 71-72 combination valve to White Post Restorations and they did a good job with that. I'm sure they could take care of your master cylinder too, and maybe the original booster and brackets. I'm not sure if they do boosters, but they might. They put a cast iron color epoxy coat on the combination valve, but their paint job was not perfect. There's minor places they missed and you can barely tell the difference between the paint and bare cast iron. It becomes more evident when it gets a little rust on it. I did touch up paint on the valve. Anyway, it would be more expensive but it would likely last a long time and you would be getting the parts that were engineered for your truck and not some generic Chinese not-made-for-your-application-but-sorta-works parts.
