alright heres the deal. under the glove box thingy on the passenger side i have a badge that says performance suspension. not sure if that means it has thr ws6 package or not. its a 87 trans am with the 4bbl 5.0. when i drive it it hardly has any body roll and has a smooth transaction going into and out of corners. also i tryed to look up the vin online to see if i could find any info but couldnt find anything. so if there is a sight you guys know of that would tell me let me know thanks.

 

Look in the console for the RPO sheet. Should say WS6 on that.

 

mine says perf. susp. as well so since i dont have rpo codes on the car just measure the front and back sway bars it should have 36mm front and 1" in the back. which i believe is the ws6 package if i recall correctly. which i am sure someone else will know for sure.

 

there is no rpo sheet so i'll go measure the sway bars once i get some calipers.

 

Really don't need to have the sway bar on the car to measure it. Just use a tape measure or if you have a diameter finder then just measure the circumference of the bar.

 

i just used a tape measure to find the right sizes myself.
