I have a 66 chevelle ss the new bb coil springs are 18 3/4" tall is that the right height for bb springs. There is no engine in my car & with the spring installed it looks like upper ball joint is pulled out toward spindle. Sb spring is 16" does this look normal

You need the car assembled with an engine and all the front sheetmetal and rolling on all 4 tires before you can work with the ride height.
