Does anyone know where I can find a Brake Fluid Distribution Block or Proportioning Valve for 69 Riviera?
I don't know much about Rivieras. You may have to resort to an adjustable replacement part from a place like Summit. I can't say much about how it would fit up, I'm just suggesting a source. What is wrong with what you have? Also, it may be that another car line like Chevrolet has the same part.
