just added a rear sway bar from an 84 z28 to my non sway bar car.Man what a difference!!I had to tap the holes for the mounting bolts because they were unthreaded, but that was the hardest part.I reduced body roll by 50% easy. if you dont have one, get one.

 

I did not know they made these cars without them!! I am glad you installed them, it actually makes the car fun to ride!! My friend did the same in his 1969 Cutlass!! It was amazing the difference!!

Good luck with your new parts!!
