I know ya'll are fans of them, so last night I took a pic of one on my wife's 06 Dodge Magnum. I don't know if you could retrofit this to a Chevelle, but that Magnum is a fine handling and riding car.:)
19" between the ball joints.

WAY too tall for a Chevelle retro-fit... ideally, about 1.5" taller than stock is perfect for a Chevelle spindle.

That's similar to the 4th gen Camaro/Firebird spindle setup. Pretty darn tall spindle there.

Those look like they`d work great....of course you`d probably have to mount the upper A arms to the valve covers....:p :thumbsup: Mark SC&C
