The first picture is of my original air cleaner to my 4 speed car. It don’t match what the manual says. The last two pictures are of the original to my wifes car before I bead blasted it and redone it the first time. I did not know of the assembly manual at the time so took measurements of that one. It was crooked from the factory and was very noticeable. I would assume that the guy that stuck these on just got it “close enough” and sent it down the line.
