Although there are some slight differences in diameter, all '84-'87 front sway bars are basically the same. The '88 front sway bar looks completely different. The sway bar for the early years is flat whereas the 88's is not.
It's a little difficult to tell in the picture, but the sway bar on this '88 suspension would not
lay flat on the ground if removed.
