What are the differences between '86-'87 and the '88-'89 makeover? I see front plastic grill and amber turn-signals. Rear taillights AC panel steering wheel
interior: steering wheel cruise control button location door panel inserts door handles power window buttons (89 specific) rear shoulder belts instead of lap belts exterior: GT model gets 7 spoke 14" alloys instead of the 10 spoke GT-S goes from 10 spoke to honeycomb wheels grille/corner lights tailights + taillight vents (89 specific) rear wiper starts from up position engine: GT-S has EGR port coming off the head instead of from exhaust manifold (89 specific) ECU altered to fix cold start issues o2 sensor is behind engine instead of in front near where manifold meets the downpipe. (not sure if this is 88-89 or simply just 89) intake rubber hose has an extra pipe attached to it.
