over 65% of the '69 coupe Road Runners had the "A87" Décor package with the upgraded interior ….. this has to be one rare RR as the least expensive when new were the quickest to get beat to death & discarded (X2 for a cheap car w/3.91s)
drive
the typical RM21 for '69 had ~$400 worth of OPTIONS, with the $102.15 3.91 axle package you are well below that ….. what else does it have? a radio?

is there a b'cast sheet?
