I haven't posted in some time.

right now im installing my r200 diff in my 72 240z and i notiiced that i have no brackets for a sway bar nor a sway bar and one of rear pasenger control arm is flipped nd not having a sway bar as well is it normal? i wanted to know how to install a sway bar on the rear i know my o73 had a sway bar.

There are two options for the rear sway bar......the factory set-up and an aftermarket set-up. With a little bit of searching in our archives section, you should find all your answers regarding rear sway bars!

Yes, the flipped rear A arm is normal. On my car, the driver side is smooth up, and the pass. side is opposite.

hmm why would nissan do that? but i changed out anyways

It is always cheeper to make one part than two...

I would guess that the rear A arms are interchangeable because the Z was a rally car. Its not only cheaper to forge 1 part instead of 2, but the interchangeable A arms means 1 less spare part to carry in the chase car also. Just my guess.

To expand on what hls30.com said..

In manufacturing there is a fixed cost with respect to tooling and fixturing. By using the same part on both sides of the car they are able to spread that fixed cost over twice as many parts. The individual parts are then cheaper. This is often referred to as economy of scale. The lower control arms are designed to function identically, within reason, regardless of the side they are mounted to.

Suspension Techniques makes an aftermarket kit that replaces the two vertical plates that locate the rear most bushing on the A arms with plates that have "ears" which are used to mount their sway bar. Very nice kit. Much better than the MSA kit that has you drilling the floorpan behind the seats.
