bumper interchange

[montego8]

I need a rear bumper for mt 50 dodge wayfarer and I found one that is off a 49 dodge cornet 4 door. The owner said it is also correct for the 49 car as well as a 50 dodge wagon. It can't be that different from mine,can it?

Here is what I've got from my parts manual D29, D30 4D, D33 2D, 1949-50 1137 698. D33 except 2D, D34 4D, Cl Cp, Cv Cp, 1950 1319 568. I'm not sure what the difference might be.
