true D-80 rear spoiler cars had different spring bars for the trunk. i believe one was a little thicker to help with the added weight of the spoiler. this is easier to verify after Nov 68 built cars as the D-80 spoiler option was listed on the cowl tag. it was not listed on the earlier 'half tag cars" .

Most 69 Z/28's did not receive the D-80 option. it was not a standard option until after the january 69 build date ( IIRC). most of these cars have been restored with the D-80 option even though it was not factory equipment,.

*side note - the ZL2 cowl induction hood was not standard equipment on the Z/28 either. which seem to go hand in hand with most restorations. 20,602 Z-28s were built in 69 of which 40% probably recieved these 2 option together. but now most restored Z's have both options.. shame really.
