Keep 'em coming guys. In my continuing research In '85 the Irocs got special valving for increased "feel" from the steering box. In '87 the Iroc Z 350 TPI cars all had J65 code rear disks. In '88 they added the serpentine belt system. In '89 the Iroc Z went from 10.5" to 11.65 rear rotors with aluminum 2 piston calipers. (only hardtops and stick shifts) This info is all from the web so who knows for sure. So in my fantasy deal I'm looking for an '89 Iroc Z hardtop at this point as cheap as I can find it. Maybe with a blown engine and trashed trans as it seems at this point i can only use the brakes, Serpentine system & steering. Opinions and experiences are appreciated
