1974 Thunderbird Bumper Pads

I'm looking to replace the bumper pads on my '74 big bird. It appears that the '75 pads have different style attachments. My question is specifically for the front wrap around pads, can '75 pads go on to a '74 bumper? I'm attaching pics of both pads.74bumperpad.jpg 75bumperpad.jpg
