69 GT350 fold down seat bumpers build date 1/9/69 Dearborn’s car

Looking for correct seat bumpers, the originals (maybe) are round but the replacements I'm seeing have are shaped to fit the receptacle plate, pictures of both are attached. The round ones look like they could be the same as the trunk lid bumpers. Which are correct?
