I removed the bar that runs across the back axle. I think its called a pan hard bar but not sure. It is the original and after I took it off I noticed it has a slight bend on it which couldn't be great. Probably happened over time. I looked in the classic industries catalog and they have listed a 1984-02 Rear Axle Tie Rod (G4659) origninal GM which looks like the bar I took out. They have also listed a1982-02 Pan Hard Bar (AD125). I was wondering whats the difference? The Tie Rod looks like what is on the car already but thats for an 84 onwards and my car is an 82.

 

Sounds like one is an original GM piece, where the other is a reproduction piece. Either should work from '82 onward. Probably a typo in the catalog.

Can also purchase an aftermarket panhard bar. Typically stronger.

Considering how much better any of the aftermarket pieces is, there's no point in buying another stock piece, especially when you have to pay to have it shipped overseas.

 

just making sure, the panhard rod *should* have a slight curve to it, like a slight smiley face...

(right? )

 

Should be straight.

 

uh oh...

 

mine has a slight curve in it


on the z28

hehe

 

There are two bars. One is a Pan Hard (AD125). This goes from the axle to a mount on the body. This should be straight.
The second bar is called the Rear Axle Tie Rod. It goes from the mount that the PHR attaches to, to the opposite side of the body, it is designed to add strength to the PHR mount. It is usually bent to allow room for the exhaust. Sometimes exhaust shops bend PHR to fit after market exhausts. Make sure your exhaust wont contact your new PHR if it's straight. Remember the PHR moves several inches up and down with suspension so the exhaust has to have good clearance.
