In addition to casting numbers being different for Chevelle, they had the 2 mounts for a 4 link type setup on the cast center section.
Some Impala axles in I think the later half of the 67 model year used the 3894860 casting number. Tube ends were different, all mounts were different and stamped codes were different.
Best way to figure out if one is legitimate is to get a pic of the letters and numbers stamped on the passenger side axle tube. Post it and we can verify if it’s legitimate.
