64 dart bumper same as valiant?

can anyone tell me if the 63-64 dart rear bumper is the same as the 64 barracuda and valiants. they look the same, but are they the same length? if it wasnt for the small bolg that starts at the bumper and goes forward id think yes for sure, but i was thinking the bumper might be wider to hug the bolg instead of flush with the body like the darts. looks more like the dart wagon bumper maybe??? i didnt get a bumper with my car so i dont know the length. can you 64 valiant/barracuda and 63-64 dart owners measure your bumper?? thanks
