Confirm the 3rd gen brackets (83 z28) will fit your current front pulley setup and 1990 vette motor/heads. If you have a serp belt now, the v belt setup the car originally had will not work. You may need 87-92 brackets/parts.
Post a picture of under your hood and front of engine and I'll let you know what you may need.
