Help with Application for these Leaf Spring Cups, Please

[JJR69COPO]

These were in a box of 1969 Camaro parts I purchased recently.

The GM Part Numbers are unreadable.

The three bolts holes that line up with the J-Nuts in the frame rails are positioned the same as standard First Gen Camaro GM Leaf Spring Cups, Part Numbers 3892752 and 3892751.

The major difference I can see is that the holes for the bolts that go through the front leaf spring bushings are set higher than the ones on the standard cups which would seem to give the car a higher stance?

The standard cups are at the bottom of the photos.

Any input on the application for these will be much appreciated.

Thank you.
