This tray fit perfectly with a 1" tall lip all the way around to trap fluids. The plastic is a little thinner than I was expecting, but since it is supported by the flooring below, it seems fine. There are two versions of this tray, and the description is not very clear. 39029375 is for Cruze with the SJQ RPO code, meaning if you have a spare tire (standard on LT and Premier models). 39029374 is for the Cruze with the 5A7 RPO code, meaning without a spare tire (L and LS models).
