Hello All ! New here but have been a mopar guy since I went to Talladega in 1970 and saw Ricard Petty's 43 Superbird on track. I just bought a 69 Coronet 440 ( body style ) with a #'s matching 383 engine & trans. On the fender tag there is the "A40" option which decodes to " 1969 only dodge spring special B package " Does anyone know what that is ? Thanks for any help on this !
