Says should be red/lt gray stripe kit but then has (91) next to it. I assume that means for 1991 models? No? Mine is a 1988 with this code. I ask because the car has been repainted its original color and i wanted to make sure the original decals are on the car. Mine are all red with red/black lower stripes

 

Wow the search option finally helped me out sorry for the post.....FYI:

Look for two numbers followed by an "A" i.e. 86A is the black/silver stripes, silver IROC-Z door decal.
88A is the black/gold stripes, gold IROC-Z door decal.
89A is the black/red stripes, red IROC-Z door decal.
90A is the silver/yellow stripes, silver IROC-Z door decal.
81A is the black/blue stripes, silver IROC-Z door decal.
