Thanks everyone.
Oh it's a 71, 72 didn't have the louvers in the trunk.
The Riviera with boat tail was built 1971-1973. The 1971 had the louvers.
"The 1971 Riviera also features GM's "Full-Flo" ventilation system and two large deck lid louvers are prominent on the trunk lid. (Unfortunately, under certain conditions a vacuum was created that sucked rain and exhaust back into the car and the "Full-Flo" ventilation was redesigned and the louvers were removed from trunk lid for the 1972 model year)."
