What is the assembly line correct 1968 Camaro vacuum break control assembly (i.e., choke pull-off) for a Rochester 4-barrel (4MV) carburetor?
According to Group 3.725 Carburetor Charts 23 and 25 of the 1967-1969 Camaro Master Parts Catalog No. 691A (June 1969), the correct vacuum break control assembly is #7034909 for all 327, 350, 396, and 427 cubic inch engines with Rochester Carburetor Model 4MV.
According to the "GM Part Number Replacements and Supersessions" Manual (August 1979), Part #7038960 replaced Part #7034909.
Last year, I bought a NOS #7038960 vacuum break (i.e., choke pull-off). It had a silver-grey front and black rear (see photos below). Note the "RP" logo on the front. It seems that all of the aftermarket choke pull-offs are an off-white color. Which color is assembly line correct?
Also, what is more correct for points in Legends judging: An incorrect-color, service replacement Rochester Products OEM part, or a correct-color aftermarket non-OEM part?
