DOC, If anyone took a close look at the SC/360 CLONE in the Hemmings mag this month, you will notice (besides the muddy footprint on the carpet) it has an under dash factory A/C system not using the one piece package tray. I think the package tray style with the round vents on either end started in 1972 and went all the way to the end of production in the Eagle in 1987. I found an '85 Eagle in a local junkyard about three years ago and it had this style that would fit on any Gremlin/Hornet/Spirit Concord or Eagle. 'The Mix'
