does anyone know the production numbers for a 1971 pontiac sport convertible with a 455 cu in motor
I presume you are speaking about a LeMans Sport convertible. I don't have an answer for you but you might try asking someone affiliated with a GTO club in your area. The two cars are very similar and some of these guys may have info that overlaps from their GTO records of the period.
