HI..Ted the sway bars are year specific but I think there is one for the years you mentioned, check their web site.

Bill that's what I did new shocks with the new sway bar its the only way to fly.

Wrench...they showed up real quick and I ordered from their web site. The instructions that come with the sway bar are almost unusable they are too small and the parts are not numbered. I downloaded the pictures and the install article by Leon Corley courtesy of Chevytrucks.org ..THANKS, Steve
