I need help identifying some 240 front bumpers.

The lower (rusty) bumper came off my 240Z. I bought the upper (clean) bumper at a swap meet but now see that the attachments to the bumper brackets are totally different. (The circled holes are for the over-rider.) The lower (rusty) bumper has the inner mounting studs 30.5 inches apart. The upper (clean) bumper has them 33.5 inches apart.

And the license plate brackets are also drilled differently.

The rusty one seemed to be original to my May 1971 240Z and fit perfectly. But what the heck is this upper one from?

Possibly from a '73 240Z when they changed the mounting to give it "slight" crash resistance.

That would be my first guess, too. It's been so long since I got rid of the 73 bumpers that I don't recall the exact differences in construction between it an the earlier style bumper that were needed to accommodate the sturdier bumper mounts.

73 bumpers still have a pair of studs, they are just farther apart to fit the much heavier bracket design. The location of the bumperettes changed as well.

The 74 early 260 skinny bumpers changed again as it was mounted to hydraulics and it had a single mount stud as I remember. This bumper seems to have that.

Another indicator is the little weld in studs (M6) alone the top inside face that mounted that rubber spacer strip that filled the gap from bumper to body with the farther out 73 and 74 bumpers.
