Please take a look at the attached pictures of the dual quad set up I purchased for installation on my 66 Skylark GS. I am concerned with the "kick down" switch and bracket. The switch and bracket are different from all other original dual quad set ups I've seen and from the switch and bracket shown in the Buick Parts Manual. It appears as though the switch will operate since the roller on the linkage of the primary carb does depress the plunger of the switch. However, the original dual quad set up's I've seen use the same "kick down" switch as the one on my single four barrel set up which operates by extending the switch shaft forward, exactly opposite from the one I purchased. Is this an "original" Buick product? If so, on what car(s) and in what year(s) was it used? Also, the seller powder coated the intake, however, he used Buick Engine Red from the 1930's. I plan to repaint the intake using the correct 1966 Buick Engine Red Hi-Temp paint. Are there any negatives to painting over the powder coat? Thanks for your help!
