E body Kelsey Hayes on an A body?

After going out to take pics, i realize I have two different spindles and brake setups. One has a bolt on lower ball joint with the tie rod end on it. The other is a one piece unit with just the hole for the ball joint. Both have 4 piston calipers although one is smaller than the other and one is not as wide as the other where the rotor goes. Will get pics later.
