Bumper Bracket Part Numbers

[Gary AAR]

I have an extra set of front bumper brackets that I thought were for a 70 Cuda with a steel bumper.  Looking at the part numbers, I'm not sure.  Wondering if someone can help.

By the 1970 Parts Catalog, a Barracuda should have the following front bumper bracket part numbers:
Steel Bumper: Inner bracket RH 2962280, LH 2962281.
              Outer bracket RH 2962284, LH 2962285.
Rubber Bumper: Inner bracket RH 2962442, LH 2962443.
               Outer bracket RH 2962446, LH 2962447.

I have a RH outer bracket stamped 2962284, which matches the parts catalog information above.  I also have a LH outer bracket stamped 2962449, which doesn't match the parts catalog.  Part number 2962449 doesn't show up in any 1970-74 parts catalogs for a barracuda or challenger.  Just doing a visual check, 2962449 looks identical to a LH outer bracket 2962285.

Anybody know where bracket 2962449 is from?  Do the inner brackets have a part number stamped on them?  I haven't cleaned the inner brackets up yet to see if they have a part number stamped on them.

Thanks for the help.
Gary.
