the garnish moldings are off a car with a big back peaked window and and peaked windshield and have vertical lines on the moldings for the door window. ALMOST fit on a 35-36 ford three window but obviously those cars dont have a peaked windshield or peaked rear window. the decklid almost looks like a 32 ford but the vertical inner lines dont match up, they get wider up by the hinge holes. dimensions on the decklid are 40 inches wide and 30.75 long
Based on the chrome ring around the handle hole on the deck lid I think it is Chevy or another GM product from aroind 1930-32.
