Sway Bar/Anti Roll Bar Size
I believe that they came with two different sizes to order when these cars "G Body's" were in production.I have 85' GP and it had a the larger one on it,it was approx. at least 1" in diameter.Go on eBay and run a search for the sway bar and then just ask the seller to give you the size,and I would do this to about 3-4 sellers and then you will know exactly what you want to know.FYI You dont have to have a account to look on eBay.
