2GA is 95-96 and 2GB is 97-99. Notable changes include headlights, bumper covers, transmissions, and engine management styles.

Hope that helps.

same as 1Ga and 1Gb (pop up headlight 90-91 and fixed headlight 92-94)

 

2ga 95-96 = 'smiley face' front bumper, 'halfmoon' reverse lights in rear bumper, yellow faded headlights most of the time, low 3-piece spoiler on all models, bottom grey trim on turbo models

2gb 97-99 = diff. bumpers and skirts, turbo models have the high turbo spoiler, non-turb's have the low 3-piece, nice headlights
