I removed the equalizer bar from my 1966 Cyclone 390 car. The width is spring loaded and adjustable. The frame side has a .990 ball and the block side has a .630 ball. I'm hoping some of the Fairlane and Comet members can tell me if this is correct for the car. The listed reproduction at Auto Krafters is not adjustable. The site doesn't like my photo extension for some reason. Any insights will be appreciated. Thanks, Chuck
