A42 - 6-way BENCH seat??1
BGR - Bowling Green plant
B3W - ????
CC3 - transparent plastic removeable roof
C49 - rear electric defogger
C60 - manual AC controls
DL8 - electric outside mirrors w/defog

GM1 - 2.59 rear axle ratio
KB2 - cast iron cylinder heads

K68 - 105 amp alternator
L98 - L-98 5.7l engine

So there you have it... medium brown metallic.
Still not sure about the 8771; mine says 8774 and is red if that helps... Sorry about the missing codes; my book doesn't have everything.
