they look exactly the same on my 4dr comet and the one that used to be on my 76 2dr maverick. the shock absorbers may be a little diffrent but the bumper seemed to be the same. i never had the 4dr's off so i dont know if the shocks mounted to the frame the same
Even if the shocks were different, the chrome outer shell is the same. Just put the shell on the other inside support and you're done...
