I'm not sure... but you might have other options. A good 72 bumper is hard to find, while a 74 is not as hard. You could sell the 72 to buy and recrome a 74. If you already have a 74 and are just looking to get rid of the over riders, then sell the 72 bumper to paid fro recroming and hole filling on the 74. Just some ideas that don't really address your question.
