do i need a pan hard rod?
there are 2 bars in my rear, looks like a Z kinda. i went over a bump and broke the lower bar. instead of welding it i just got a bracket n bolted it back together when i go at about 50/60mph the back of car sways so would a pan hard rod be the solution? 1 new rod will replace the 2 that i originally have?

Re: do i need a pan hard rod?
The only way to replace those 2 bars is to get a Watts link setup http://fays2.net/fays2_watts_link_21_.html or completely redesign the rear suspension into a 4-link setup.
In other words? Not really. The top is a brace for the chassis. The bottom is a Panhard Bar & is what actually controls the axle movement side to side.

YES, buy a new panhard bar. It is the only thing that locates the rear end side to side.

The PHB (bottom one) indeed locates the rear side-to-side.
Our 2020 is very cost effective.

Ramey, to hijack the thread for a moment: No company (Granatelli had a boxed version at one point. See the review below) fabs the upper panhard brace. Any comment on why that would be so?

We build a relocation PHB brace to help exhaust clear. But as for standard location we usually just retain the factory piece. It seems to be ok but doesn't work for the relocation.
Building a standard location one is on a design list somewhere but demand is pretty low. It would be good to offer, I'd imagine, as a completely refurbished suspension with that stock stamped piece doesn't look so great.

Re: do i need a pan hard rod?
What effect would that have of stiffening the rear chassis? Any? It almost seems like it might help with some of the random hatch squeaks and stuff a lot of us have. I think I'll take a look when I'm under there this weekend.

Re: do i need a pan hard rod?
YES you need that panhard, listen to these people, lol
cal30sniper- I doubt an aftermarket piece would do anything that SFC's haven't already done. That is basically a strut brace in a meaningless place. Struts are leaning inward and create various angles against the road that are handled at extreme loads against the strut mounts, so STB's make a big difference when you tie them together and make them an immovable object taking force in unison.
I doubt the rear would make a difference at all. The only load that area ever will see is when it is locating the rear axle, and the slight flex the resistance of the rear shocks are causing against the floorpan.
