I'm looking at getting an aftermarket panhard bar for my lower trans am. Will I need relocation brackets

 

Are you going to do a whole diferential upgrade?

 

Just get the adjustable PHB and you will be fine. Relocation brackets are usually associated with the rearend LCA's, and are a good mod for no more than it costs. Most definitely do weld-on style if you do though. Give me a call... MWC has all these parts on sale now!
