Sledgehammers are cheap. I'll give you links to home Depot and many other places that are close to you to do the modifications.

That was the point with backdating, to restore the orginal lines of the design.

Model year '73 only required a 5mph bumper in front. There are a good deal of '73 unique bumper designs out there and for many makes and models. Sometimes they are very well done and show little difference from a '72 of the same model. Other times they are in between what a '72 and a '74 looks like. For some reason when they went front and rear in '74 that's when the ugly started for most models. So, what you meant was clear to me anyway.
