I broke my rear sway bar and linkage .And since I was going to a 1 1/4 front bar ,7/8`s rear bar.I used a Herb Adams kit .Its a lot stronger and better design.Because it uses front sway bar bushings of varying sizes. I use a grease able black urethane myself but that is up to you.
I don`t drive through drive through car washes on both of my cars. 1979 Z28 RS Camaro ,and 1981 El Camino SS.Both Pro-touring Car because they set so low.
