What are the differences between '86-'87 and the '88-'89 makeover?

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.
